rev 1.0 k7p161811m 512kx36 & 1mx18 sram k7p163611m dec. 2001 - 4 - function description the k7p163611m and k7p161811m are 18,874,368 bit synchronous pipeline mode sram. it is organized as 524,288 words of 36 bits(or 1,048,576 words of 18 bits)and is implemented in samsung s advanced cmos technology. single differential hstl level k clocks are used to initiate read/write operation and all internal operations are self-timed. at the rising edge of k clock, all addresses, write enables, synchronous select and data ins are registered internally. data outs are updated from output registers at the next rising edge of k clock. an internal write data buffer allows write data to follow one cycle af ter addresses and controls. the package is 119(7x17) ball grid array with balls on a 1.27mm pitch. mode control there are two mode control select pins (m 1 and m 2 ) used to set the proper read protocol. this sram supports single clock pipelined operating mode. for proper specified device operation, m 1 must be connected to v ss and m 2 must be connected to v ddq . these mode pins must be set at power-up and must not change during device operation. power-up/power-down supply voltage sequencing the following power-up supply voltage application is recommended: v ss , v dd , v ddq , v ref , then v in . v dd and v ddq can be applied simultaneously, as long as v ddq does not exceed v dd by more than 0.5v during power-up. the following power-down supply voltage removal sequence is recommended: v in , v ref , v ddq , v dd , v ss . v dd and v ddq can be removed simultaneously, as long as v ddq does not exceed v dd by more than 0.5v during power-down. sleep mode sleep mode is a low power mode initiated by bringing the asynchronous zz pin high. during sleep mode, all other inputs are ignor ed and outputs are brought to a high-impedance state. sleep mode current and output high-z are guaranteed after the specified sleep mode enable time. during sleep mode the memory array data content is preserved. sleep mode must not be initiated until after all pending operations have completed, since any pending operation will not guaranteed once sleep mode is initiated. normal opera- tions can be resumed by bringing the zz pin low, but only after the specified sleep mode recovery time. bypass read operation bypass read operation occurs when the last write operation is followed by a read operation where write and read addresses are identical. for this case, data outputs are from the data in registers instead of sram array. bypass read operation occurs on a b yte to byte basis. if only one byte is written during a write operation but a read operation is required on the same address, a partial bypass read operation occurs since the new byte data is from the data in registers while the remaing bytes are from sram arry. write operation(late write) during write operations, addresses and controls are registered at the first rising edge of k clock and data inputs are registere d at the following rising edge of k clock. write addresses and data inputs are stored in the data in registers until the next write opera tion, and only at the next write opeation are data inputs fully written into sram array. byte write operation is supported using sw[ a:d] and the timing of sw[ a:d] is the same as the sw signal. programmable impedance output driver the data output driver impedance is adjusted by an external resistor, rq, connected between zq pin and v ss , and is equal to rq/5. for example, 250 w resistor will give an output impedance of 50 w . output driver impedance tolerance is 15% by test(10% by design) and is periodically readjusted to reflect the changes in supply voltage and temperature. impedance updates occur early in cycles that do not activate the outputs, such as deselect cycles. they may also occur in cycles initiated with g high. in all cases impedance updates are transparent to the user and do not produce access time "push-outs" or other anomalous behavior in the sram. imped- ance updates occur no more often than every 32 clock cycles. clock cycles are counted whether the sram is selected or not and proceed regardless of the type of cycle being executed. therefore, the user can be assured that after 33 continuous read cycles have occurred, an impedance update will occur the next time g are high at a rising edge of the k clock. there are no power up requirements for the sram. however, to guarantee optimum output driver impedance after power up, the sram needs 1024 non- read cycles. the output buffers can also be programmed in a minimum impedance configuration by connecting zq to v ss or v ddq . read operation during read operations, addresses and controls are registered during the first rising edge of k clock and then the internal arra y is read between first rising and falling edges of k clock. data outputs are updated from output registers off the falling edge of k clock. during consecutive read operations where the address is the same, the data output must be held constant without any glitches. th is characteristic is because the sram will be read by devices that will operate slower than the sram frequency and will require mul ti- ple sram cycles to perform a single read operation.
