MH16S64DAMD -6,-7,-8
1073741824-BIT (16777216 - WORD BY 64-BIT)Synchronous DRAM
DESCRIPTION
The MH16S64DAMD is 16777216 - word by 64-bit Synchronous DRAM module. This consists of sixteen industry standard 8Mx8 Synchronous DRAMs in TSOP and one industory standard EEPROM in TSSOP. The mounting of TSOP on a card edge Dual Inline package provides any application where high densities and large quantities of memory are required. This is a socket type - memory modules, suitable for easy interchange or addition of modules.

PIN FUNCTION
CK (CK0 ~ CK3) Input Master Clock:All other inputs are referenced to the ris ing edge of CK Clock Enable:CKE controls internal clock.When CKE is low,internal clock for the following cycle is ceased. CKE is also used to select auto / self refresh. After self refresh mode is started, CKE becomes asynchronous input.Self refresh is maintained as long as CKE is low. Chip Select: When /S is high,any command means No Operation. Combination of /RAS,/CAS,/WE defines basic commands. A0-11 specify the Row/Column Address in conjunction with BA.The Row Address is specified by A0-11.The Column Address is specified by A0-8.A10 is also used to indicate precharge option.When A10 is high at a read / write command, an auto precharge is performed. When A10 is high at a precharge command, all banks are precharged. Bank Address:BA0,1 is not simply BA.BA specifies the bank to which a command is applied.BA0,1 must be set with ACT,PRE,READ,WRITE commands

BASIC FUNCTIONS
The MH16S64DAMD provides basic functions,bank(row)activate,burst read / write, bank(row)precharge,and auto / self refresh. Each command is defined by control signals of /RAS,/CAS and /WE at CK rising edge. In addition to 3 signals,/S,CKE and A10 are used as chip select,refresh option,and precharge option,respectively. To know the detailed definition of commands please see the command truth table.
CK /S /RAS /CAS /WE CKE A10
Chip Select : L=select, H=deselect Command Command Command Ref resh Option @ref resh command Precharge Option @precharge or read/write command def ine basic commands
Activate(ACT) [/RAS =L, /CAS = /WE =H] ACT command activates a row in an idle bank indicated by BA. Read(READ) [/RAS =H,/CAS =L, /WE =H] READ command starts burst read from the active bank indicated by BA.First output data appears after /CAS latency. When A10 =H at this command,the bank is deactivated after the burst read(auto-precharge,READA). Write(WRITE) [/RAS =H, /CAS = /WE =L] WRITE command starts burst write to the active bank indicated by BA. Total data length to be written is set by burst length. When A10 =H at this command, the bank is deactivated after the burst write(auto-precharge,WRITEA). Precharge(PRE) [/RAS =L, /CAS =H,/WE =L] PRE command deactivates the active bank indicated by BA. This command also terminates burst read / write operation. When A10 =H at this command, both banks are deactivated(precharge all, PREA). Auto-Refresh(REFA) [/RAS =/CAS =L, /WE =CKE =H] REFA command starts auto-refresh cycle. Refresh address including bank address are generated internally. After this command, the banks are precharged automatically.

POWER ON SEQUENCE
Before starting normal operation, the following power on sequence is necessary to prevent a SDRAM from damaged or malfunctioning. 1. Apply power and start clock. Attempt to maintain CKE high, DQMB0-7 high and NOP condition at the inputs. 2. Maintain stable power, stable clock, and NOP input conditions for a minimum of 200us. 3. Issue precharge commands for all banks. (PRE or PREA) 4. After all banks become idle state (after tRP), issue 8 or more auto-refresh commands. 5. Issue a mode register set command to initialize the mode register. After these sequence, the SDRAM is idle state and ready for normal operation.
MODE REGISTER
Burst Length, Burst Type and /CAS Latency can be programmed by setting the mode register(MRS). The mode register stores these date until the next MRS command, which may be issue when both banks are in idle state. After tRSC from a MRS command, the SDRAM is ready for new command.

OPERATION DESCRIPTION
BANK ACTIVATE One of four banks is activated by an ACT command. An bank is selected by BA0-1. A row is selected by A0-11. Multiple banks can be active state concurrently by issuing multiple ACT commands. Minimum activation interval between one bank and another bank is tRRD. PRECHARGE An open bank is deactivated by a PRE command. A bank to be deactivated is designated by BA0-1. When multiple banks are active, a precharge all command (PREA, PRE + A10=H) deactivates all of open banks at the same time. BA0-1 are "Don't Care" in this case. Minimum delay time of an ACT command after a PRE command to the same bank is tRP. Bank Activation and Precharge All (BL=4, CL=2)

READ A READ command can be issued to any active bank. The start address is specified by A0-8 (x8) . 1st output data is available after the /CAS Latency from the READ. The consecutive data length is defined by the Burst Length. The address sequence of the burst data is defined by the Burs t Type. Minimum delay time of a READ command after an ACT command to the same bank is tRCD. When A10 is high at a READ command, auto-precharge (READA) is performed. Any command (READ, WRITE, PRE, ACT, TBST) to the same bank is inhibited till the internal precharge is complete. The internal precharge starts at the BL after READA. The next ACT command can be issued after (BL + tRP) from the previous READA. In any case, tRCD+BL > tRASmin must be met.

WRITE A WRITE command can be issued to any active bank. The start address is specified by A0-8 (x8). 1st input data is set at the same cycle as the WRITE. The consecutive data length to be written is defined by the Burst Length. The address sequence of burst data is defined by the Burs t Type. Minimum delay time of a WRITE command after an ACT command to the same bank is tRCD. From the last input data to the PRE command, the write recovery time (tWR) is required. When A10 is high at a WRITE command, auto-precharge (WRITEA) is performed. Any command (READ, WRITE, PRE, ACT, TBST) to the same bank is inhibited till the internal precharge is complete. The internal precharge starts at tWR after the last input data cycle. The next ACT command can be issued after (BL + tWR -1 + tRP) from the previous WRITEA. In any case, tRCD + BL + tWR -1 > tRASm in must be met.
