Description
The 512-Mbit Double-Data-Rate SDRAM is a high-speed CMOS, dynamic random-access memory containing 536,870,912 bits. It is internally configured as a quad-bank DRAM. The 512-Mbit Double-Data-Rate SDRAM uses a double-data-rate architecture to achieve high-speed operation. The double data rate architecture is essentially a 2n prefetch architecture with an interface designed to transfer two data words per clock cycle at the I/O pins. A single read or write access for the 512-Mbit Double-Data-Rate SDRAM effectively consists of a single 2n-bit wide, one clock cycle data transfer at the internal DRAM core and two corresponding n-bit wide, one-half-clock-cycle data transfers at the I/O pins. A bidirectional data strobe (DQS) is transmitted externally, along with data, for use in data capture at the receiver. DQS is a strobe transmitted by the DDR SDRAM during Reads and by the memory controller during Writes. DQS is edge-aligned with data for Reads and center-aligned with data for Writes. The 512-Mbit Double-Data-Rate SDRAM operates from a differential clock (CK and CK; the crossing of CK going HIGH and CK going LOW is referred to as the positive edge of CK). Commands (address and control signals) are registered at every positive edge of CK. Input data is registered on both edges of DQS, and output data is referenced to both edges of DQS, as well as to both edges of CK. Read and write accesses to the DDR SDRAM are burst oriented; accesses start at a selected location and continue for a programmed number of locations in a programmed sequence. Accesses begin with the registration of an Active command, which is then followed by a Read or Write command. The address bits registered coincident with the Active command are used to select the bank and row to be accessed. The address bits registered coincident with the Read or Write command are used to select the bank and the starting column location for the burst access. The DDR SDRAM provides for programmable Read or Write burst lengths of 2, 4 or 8 locations. An Auto Precharge function may be enabled to provide a self-timed row precharge that is initiated at the end of the burst access. As with standard SDRAMs, the pipelined, multibank architecture of DDR SDRAMs allows for concurrent operation, thereby providing high effective bandwidth by hiding row precharge and activation time. An auto refresh mode is provided along with a power-saving power-down mode. All inputs are compatible with the Industry Standard for SSTL_2. All outputs are SSTL_2, Class II compatible. Note: The functionality described and the timing specifications included in this data sheet are for the DLL Enabled mode of operation.

Exceptions are covered in the notes below. 3) Current state definitions: Idle: The bank has been precharged, and tRP has been met. Row Active: A row in the bank has been activated, and tRCD has been met. No data bursts/accesses and no register accesses are in progress. Read: A Read burst has been initiated, with Auto Precharge disabled, and has not yet terminated or been terminated. Write: A Write burst has been initiated, with Auto Precharge disabled, and has not yet terminated or been terminated. 4) The following states must not be interrupted by a command issued to the same bank. Precharging: Starts with registration of a Precharge command and ends when tRP is met. Once tRP is met, the bank is in the idle state. Row Activating: Starts with registration of an Active command and ends when tRCD is met. Once tRCD is met, the bank is in the "row active" state. Read w/Auto Precharge Enabled: Starts with registration of a Read command with Auto Precharge enabled and ends when tRP has been met. Once tRP is met, the bank is in the idle state. Write w/Auto Precharge Enabled: Starts with registration of a Write command with Auto Precharge enabled and ends when tRP has been met. Once tRP is met, the bank is in the idle state. Deselect or NOP commands, or allowable commands to the other bank should be issued on any clock edge occurring during these states. Allowable commands to the other bank are determined by its current state and according to Table 16. 5) The following states must not be interrupted by any executable command; Deselect or NOP commands must be applied on each positive clock edge during these states. Refreshing: Starts with registration of an Auto Refresh command and ends when tRFC is met. Once tRFC is met, the DDR SDRAM is in the "all banks idle" state. Accessing Mode Register: Starts with registration of a Mode Register Set command and ends when tMRD has been met. Once tMRD is met, the DDR SDRAM is in the "all banks idle" state. Precharging All: Starts with registration of a Precharge All command and ends when tRP is met. Once tRP is met, all banks is in the idle state. 6) All states and sequences not shown are illegal or reserved. 7) Not bank-specific; requires that all banks are idle. 8) Reads or Writes listed in the Command/Action column include Reads or Writes with Auto Precharge enabled and Reads or Writes with Auto Precharge disabled. 9) May or may not be bank-specific; if all/any banks are to be precharged, all/any must be in a valid state for precharging. 10) Not bank-specific; BURST TERMINATE affects the most recent Read burst, regardless of bank. 11) Requires appropriate DM masking.

1) This table applies when CKE n-1 was HIGH and CKE n is HIGH (see Table 14: Clock Enable (CKE) and after tXSNR/tXSRD has been met (if the previous state was self refresh). 2) This table describes alternate bank operation, except where noted, i.e., the current state is for bank n and the commands shown are those allowed to be issued to bank m (assuming that bank m is in such a state that the given command is allowable). Exceptions are covered in the notes below. 3) Current state definitions: Idle: The bank has been precharged, and tRP has been met. Row Active: A row in the bank has been activated, and tRCD has been met. No data bursts/accesses and no register accesses are in progress. Read: A Read burst has been initiated, with Auto Precharge disabled, and has not yet terminated or been terminated. Write: A Write burst has been initiated, with Auto Precharge disabled, and has not yet terminated or been terminated. Read with Auto Precharge Enabled: See 10). Write with Auto Precharge Enabled: See 10). 4) AUTO REFRESH and Mode Register Set commands may only be issued when all banks are idle. 5) A BURST TERMINATE command cannot be issued to another bank; it applies to the bank represented by the current state only. 6) All states and sequences not shown are illegal or reserved. 7) Reads or Writes listed in the Command/Action column include Reads or Writes with Auto Precharge enabled and Reads or Writes with Auto Precharge disabled. 8) Requires appropriate DM masking.

9) Concurrent Auto Precharge: This device supports "Concurrent Auto Precharge". When a read with auto precharge or a write with auto precharge is enabled any command may follow to the other banks as long as that command does not interrupt the read or write data transfer and all other limitations apply (e.g. contention between READ data and WRITE data must be avoided). The minimum delay from a read or write command with auto precharge enable, to a command to a different banks is summarized in Table 17. 10) A Write command may be applied after the completion of data output.

DDR400 conditions apply for all clock frequencies above 166 MHz Under all conditions, VDDQ must be less than or equal to VDD. Peak to peak AC noise on VREF may not exceed 2% VREF.DC. VREF is also expected to track noise variations in VDDQ. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to VREF, and must track variations in the DC level of VREF. Inputs are not recognized as valid until VREF stabilizes. VID is the magnitude of the difference between the input level on CK and the input level on CK. The ratio of the pull-up current to the pull-down current is specified for the same temperature and voltage, over the entire temperature and voltage range, for device drain to source voltage from 0.25 to 1.0 V. For a given output, it represents the maximum difference between pull-up and pull-down drivers due to process variation. Values are shown per pin.

AC Characteristics
Notes 1-5 apply to the following Tables; Electrical Characteristics and DC Operating Conditions, AC Operating Conditions, IDD Specifications and Conditions, and Electrical Characteristics and AC Timing. Notes 1. All voltages referenced to VSS. 2. Tests for AC timing, IDD, and electrical, AC and DC characteristics, may be conducted at nominal reference/supply voltage levels, but the related specifications and device operation are guaranteed for the full voltage range specified. 3. Figure 4 represents the timing reference load used in defining the relevant timing parameters of the part. It is not intended to be either a precise representation of the typical system environment nor a depiction of the actual load presented by a production tester. System designers will use IBIS or other simulation tools to correlate the timing reference load to a system environment. Manufacturers will correlate to their production test conditions (generally a coaxial transmission line terminated at the tester electronics). 4. AC timing and IDD tests may use a VIL to VIH swing of up to 1.5 V in the test environment, but input timing is still referenced to VREF (or to the crossing point for CK, CK), and parameter specifications are guaranteed for the specified AC input levels under normal use conditions. The minimum slew rate for the input signals is 1 V/ns in the range between VIL(AC) and VIH(AC). 5. The AC and DC input level specifications are as defined in the SSTL_2 Standard (i.e. the receiver effectively switches as a result of the signal crossing the AC input level, and remains in that state as long as the signal does not ring back above (below) the DC input LOW (HIGH) level). 6. For System Characteristics like Setup & Holdtime Derating for Slew Rate, I/O Delta Rise/Fall Derating, DDR SDRAM Slew Rate Standards, Overshoot & Undershoot specification and Clamp V-I characteristics see the latest Industry specification for DDR components.

2) Input slew rate 1 V/ns for DDR400, DDR333 3) The CK/CK input reference level (for timing reference to CK/CK) is the point at which CK and CK cross: the input reference level for signals other than CK/CK, is VREF. CK/CK slew rate are 1.0 V/ns. 4) Inputs are not recognized as valid until VREF stabilizes. 5) The Output timing reference level, as measured at the timing reference point indicated in AC Characteristics (note 3) is VTT. 6) For each of the terms, if not already an integer, round to the next highest integer. tCK is equal to the actual system clock cycle time. 7) tHZ and tLZ transitions occur in the same access time windows as valid data transitions. These parameters are not referred to a specific voltage level, but specify when the device is no longer driving (HZ), or begins driving (LZ). 8) Fast slew rate 1.0 V/ns , slow slew rate 0.5 V/ns and < 1 V/ns for command/address and CK & CK slew rate > 1.0 V/ns, measured between VIH(ac) and VIL(ac). 9) These parameters guarantee device timing, but they are not necessarily tested on each device. 10) The specific requirement is that DQS be valid (HIGH,LOW, or some point on a valid transition) on or before this CK edge. A valid transition is defined as monotonic and meeting the input slew rate specificationsof the device. When no writes were previously in progress on the bus, DQS will be transitioning from Hi-Z to logic LOW. If a previous write was in progress, DQS could be HIGH, LOW at this time, depending on tDQSS. 11) The maximum limit for this parameter is not a device limit. The device operates with a greater value for this parameter, but system performance (bus turnaround) degrades accordingly.
