GENERAL DESCRIPTION
The K7P323674C and K7P321874C are 37,748,736 bit Synchronous Pipeline Mode SRAM. It is organized as 1,048,576 words of 36
bits(or 2,097,152 words of 18 bits)and is implemented in SAMSUNG′s advanced CMOS technology.
Single differential HSTL level K clocks are used to initiate the 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 edge of the next rising edge of the K clock. An internal write data buffer allows write data to follow one
cycle after addresses and controls. The package is 119(7x17) Ball Grid Array with balls on a 1.27mm pitch.

K7P323674C
K7P321874C
1Mx36 & 2Mx18 SRAM
Read Operation
During reads, the address is registered during the frist clock edge, the internal array is read between this first edge and the second
edge, and data is captured in the output register and driven to the CPU during the second clock edge. SS is driven low during this
cycle, signaling that the SRAM should drive out the data.
During consecutive read cycles where the address is the same, the data output must be held constant without any glitches. This
characteristic is because the SRAM will be read by devices that will operate slower than the SRAM frequency and will require multi-
ple SRAM cycles to perform a single read operation.
Write(Store) Operation
All addresses and SW are sampled on the clock rising edge. SW is low on the rising clock. Write data is sampled on the rising clock,
one cycle after write address and SW have been sampled by the SRAM. SS will be driven low during the same cycle that the
Address, SW and SW[a:d] are valid to signal that a valid operation is on the Address and Control Input.
Pipelined write are supported. This is done by using write data buffers on the SRAM that capture the write addresses on one write
cycle, and write the array on the next write cycle. The "next write cycle" can actually be many cycles away, broken by a series of
read cycles. Byte writes are supported. The byte write signals SW[a:d] signal which 9-bit bytes will be writen. Timing of SW[a:d] is the
same as the SW signal.
Bypass Read Operation
Since write data is not fully written into the array on first write cycle, there is a need to sense the address in case a future read is to be
done from the location that has not been written yet. For this case, the address comparator check to see if the new read address is
the same as the contents of the stored write address Latch. If the contents match, the read data must be supplied from the stored
write data latch with standard read timing. If there is no match, the read data comes from the SRAM array. The bypassing of the
SRAM array occurs on a byte by byte basis. If one byte is written and the other bytes are not, read data from the last written will have
new byte data from the write data buffer and the other bytes from the SRAM array.
Programmable Impedance Output Buffer Operation
This HSTL Late Write SRAM has been designed with programmable impedance output buffers. The SRAMs output buffer impedance
can be adjusted to match the system data bus impedance, by connecting a external resistor (RQ) between the ZQ pin of the SRAM
and VSS. The value of RQ must be five times the value of the intended line impedance driven by the SRAM. For example, a 250Ω
resistor will give an output buffer impedance of 50Ω. The allowable range of RQ is from 175Ω to 350Ω. Internal circuits evaluate and
periodically adjust the output buffer impedance, as the impedance is affected by drifts in supply voltage and temperature. One evalu-
ation occurs every 32 clock cycles, with each evaluation moving the output buffer impedance level only one step at a time toward the
optimum level. Impedance updates occur when the SRAM is in High-Z state, and thus are triggered by write and deselect operations.
Updates will also be triggered with G HIGH initiated High-Z state, providing the specified G setup and hold times are met. Impedance
match is not instantaneous upon power-up. In order to guarantee optimum output driver impedance, the SRAM requires a minimum
number of non-read cycles (1,024) after power-up. The output buffers can also be programmed in a minimum impedance configura-
tion by connecting ZQ to VSS or VDDQ.
Mode Control
There are two mode control select pins (M1 and M2) used to set the proper read protocol. This SRAM supports single clock pipelined
operating mode. For proper specified device operation, M1 must be connected to VSS and M2 must be connected to VDDQ. 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: VSS, VDD, VDDQ, VREF, then VIN. VDD and VDDQ can be applied
simultaneously, as long as VDDQ does not exceed VDD by more than 0.5V during power-up. The following power-down supply voltage
removal sequence is recommended: VIN, VREF, VDDQ, VDD, VSS. VDD and VDDQ can be removed simultaneously, as long as VDDQ
does not exceed VDD 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 ignored
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, as any pending operation is not guaranteed to properly complete after sleep mode is initiated.
Normal operations can be resumed by bringing the ZZ pin low, but only after the specified sleep mode recovery time.

IEEE 1149.1 TEST ACCESS PORT AND BOUNDARY SCAN-JTAG
This part contains an IEEE standard 1149.1 Compatible Teat Access Port(TAP). The package pads are monitored by the Serial Scan
circuitry when in test mode. This is to support connectivity testing during manufacturing and system diagnostics. Internal data is not
driven out of the SRAM under JTAG control. In conformance with IEEE 1149.1, the SRAM contains a TAP controller, Instruction Reg-
ister, Bypass Register and ID register. The TAP controller has a standard 16-state machine that resets internally upon power-up,
therefore, TRST signal is not required. It is possible to use this device without utilizing the TAP. To disable the TAP controller without
interfacing with normal operation of the SRAM, TCK must be tied to VSS to preclude mid level input. TMS and TDI are designed so an
undriven input will produce a response identical to the application of a logic 1, and may be left unconnected. But they may also be
tied to VDD through a resistor. TDO should be left unconnected.

NOTE :
1. Places DQs in Hi-Z in order to sample all input data regardless of
other SRAM inputs.
2. TDI is sampled as an input to the first ID register to allow for the serial
shift of the external TDI data.
3. Bypass register is initiated to VSS when BYPASS instruction is
invoked. The Bypass Register also holds serially loaded TDI when
exiting the Shift DR states.
