18mb 1x2lp, hstl, rev 1.1 1 / 25 november 8, 2002 sony ? ram ? 33/4/5 cxk79m36c162gb 18mb 1x2lp hstl high speed synchronous srams (512kb x 36) preliminary description the cxk79m36c162gb is a high speed cmos synchronous static ram with common i/o pins. it is manufactured in com- pliance with the jedec-standard 209 pin bga package pinout defined for sigmaram ? devices. it integrates input registers, high speed ram, output registers, and a two-deep write buffer onto a single monolithic ic. double data rate (ddr) pipelined (pl) read operations and late write (lw) write operations are supported, providing a high-performance user interface. positive and negative output clocks are provided for applications requiring source-synchronous operation. all address and control input signals are registered on the rising edge of the ck differential input clock. during read operations, output data is driven valid twice, from both the rising and falling edges of ck, beginning one full cycle after the address and control signals are registered. during write operations, input data is registered twice, on both the rising and falling edges of ck, beginning one full cycle after the address and control signals are registered. because two pieces of data are always transferred during read and write operations, the least significant address bit of the in- ternal memory array is not available as an external address pin to this device. consequently, the number of external address pins available to the device is one less than the specified depth of the device (i.e. the 512kb x 36 device has 18, not 19, external address pins). and, the user cannot choose the order in which the two pieces of data are read. read data is always provided in the same order in which it is written. output drivers are series-terminated, and output impedance is programmable via the zq control pin. when an external resistor rq is connected between zq and v ss , the impedance of the sram?s output drivers is set to ~rq/5. 300 mhz operation (600 mbps) is obtained from a single 1.8v power supply. jtag boundary scan interface is provided using a subset of ieee standard 1149.1 protocol. features 3 speed bins cycletime/data access time -33 3.3ns / 1.8ns -4 4.0ns / 2.1ns -5 5.0ns / 2.3ns single 1.8v power supply (v dd ): 1.7v (min) to 1.95v (max) dedicated output supply voltage (v ddq ): 1.4v (min) to v dd (max) hstl-compatible i/o interface with dedicated input reference voltage (v ref ): v ddq /2 typical common i/o double data rate (ddr) data transfers pipelined (pl) read operations late write (lw) write operations burst capability with internally controlled linear burst address sequencing burst length of two or four, with automatic address wrap full read/write data coherency differential input clocks (ck and ck ) data-referenced output clocks (cq1, cq1 , cq2, cq2 ) programmable output driver impedance via dedicated control pin (zq) depth expansion capability (2 or 4 banks) via programmable chip enables (e2, e3, ep2, ep3) jtag boundary scan (subset of ieee standard 1149.1) 209 pin (11x19), 1mm pitch, 14mm x 22mm ball grid array (bga) package

sony ? ram preliminary 18mb 1x2lp, hstl, rev 1.1 6 / 25 november 8, 2002 cxk79m36c162gb ? burst (continue) operations because two pieces of data are always transferred during read and write operations, the least significant address bit (a0) of the internal memory array is not available as an external address pin to these devices. rather, the address bit is set to ?0? internally prior to the first data transfer and set to ?1? internally prior to the second data transfer. consequently, the two pieces of data transferred during read and write operations are always read in the same address sequence in which they are written. burst operations follow the simple address sequence depicted in the table below: one (1) continue operation may be initiated after a read or write operation is initiated to burst transfer four (4) distinct piec- es of data per single external address input. if a second (2nd) continue operation is initiated, the internal address wraps back to the initial external (base) address. depth expansion depth expansion in these devices is supported via programmable chip enables e2 and e3. the active levels of e2 and e3 are programmable through the static inputs ep2 and ep3 respectively. when ep2 is tied ?high?, e2 functions as an active-high input. when ep2 is tied ?low?, e2 functions as an active-low input. similarly, when ep3 is tied ?high?, e3 functions as an active-high input. and, when ep3 is tied ?low?, e3 functions as an active-low input. the programmability of e2 and e3 allows four banks of depth expansion to be accomplished with no additional logic. by programming e2 and e3 of four devices in a binary sequence (00, 01, 10, 11), and by driving e2 and e3 with external address signals, the four devices can be made to look like one larger device. when these devices are deselected via chip enable e1 , the output clocks continue to toggle. however, when these devices are deselected via programmable chip enables e2 or e3, the output clocks are forced to a hi-z state. see the clock truth table for further information. output driver impedance control the impedance of the data and clock output drivers in these devices can be controlled via the static input zq. when an ex- ternal impedance matching resistor (rq) is connected between zq and v ss , output driver impedance is set to one-fifth the value of the resistor, nominally. see the dc electrical characteristics section for further information. output driver impedance is updated whenever the data output drivers are in an inactive (high-z) state. see the clock truth table section for information concerning which commands deactivate the data output drivers. at power up, 8192 clock cycles followed by any command that deactivates the data output drivers are required to ensure that the output impedance has reached the desired value. note : the impedance of the output drivers will drift somewhat due to changes in temperature and voltage. consequently, during operation, the output drivers should be deactivated periodically in order to update the output impedance and ensure that it remains within specified tolerances. power-up sequence for reliability purposes, sony recommends that power supplies power up in the following sequence: v ss ,v dd ,v ddq ,v ref , and inputs. v ddq should never exceed v dd . if this power supply sequence cannot be met, a large bypass diode may be re- quired between v dd and v ddq . please contact sony memory application department for further information. a1 a1 sequence key 1st (base) address 0 1 a1 2nd address 1 0 a1

sony ? ram preliminary 18mb 1x2lp, hstl, rev 1.1 19 / 25 november 8, 2002 cxk79m36c162gb tap registers tap registers are serial shift registers that capture serial input data (from tdi) on the rising edge of tck, and drive serial output data (to tdo) on the subsequent falling edge of tck. they are divided into two groups: ?instruction registers? (ir), which are manipulated via the ?ir? states in the tap controller, and ?data registers? (dr), which are manipulated via the ?dr? states in the tap controller. instruction register (ir - 3 bits) the instruction register stores the various tap instructions supported by these devices. it is loaded with the idcode in- struction at power-up, and when the tap controller is in the ?test-logic reset? and ?capture-ir? states. it is inserted be- tween tdi and tdo when the tap controller is in the ?shift-ir? state, at which time it can be loaded with a new instruction. however, newly loaded instructions are not executed until the tap controller has reached the ?update-ir? state. the instruction register is 3 bits wide, and is encoded as follows: bit 0 is the lsb of the instruction register, and bit 2 is the msb. when the instruction register is selected, tdi serially shifts data into the msb, and the lsb serially shifts data out through tdo. code (2:0) instruction description 000 extest-a loads the individual logic states of all signals composing the sram?s i/o ring into the boundary scan register when the tap controller is in the ?capture-dr? state, and inserts the b-scan register between tdi and tdo when the tap controller is in the ?shift-dr? state. also enables the sram?s data and clock output drivers, and moves the contents of the b-scan register associated with the data and clock output signals to the input side of the sram?s out- put register. the sram?s input clock can then be used to transfer the b-scan register contents directly to the data and clock output pins (the input clock controls the sram?s output regis- ter). note that newly captured and/or shifted b-scan register contents do not appear at the input side of the sram?s output register until the tap controller has reached the ?update- dr? state. see the boundary scan register description for more information. 001 idcode loads a predefined device- and manufacturer-specific identification code into the id register when the tap controller is in the ?capture-dr? state, and inserts the id register between tdi and tdo when the tap controller is in the ?shift-dr? state. see the id register description for more information. 010 sample-z loads the individual logic states of all signals composing the sram?s i/o ring into the boundary scan register when the tap controller is in the ?capture-dr? state, and inserts the b-scan register between tdi and tdo when the tap controller is in the ?shift-dr? state. also disables the sram?s data and clock output drivers. see the boundary scan register description for more information. 011 private do not use. reserved for manufacturer use only. 100 sample loads the individual logic states of all signals composing the sram?s i/o ring into the boundary scan register when the tap controller is in the ?capture-dr? state, and inserts the b-scan register between tdi and tdo when the tap controller is in the ?shift-dr? state. see the boundary scan register description for more information. 101 private do not use. reserved for manufacturer use only. 110 private do not use. reserved for manufacturer use only. 111 bypass loads a logic ?0? into the bypass register when the tap controller is in the ?capture-dr? state, and inserts the bypass register between tdi and tdo when the tap controller is in the ?shift-dr? state. see the bypass register description for more information.
