FUNCTION DESCRIPTION

256Kx36 & 512Kx18 SRAM

The K7P803666M and K7P801866M are 9,437,184 bit Synchronous Pipeline Burst Mode SRAM devices. They are organized as

262,144 words by 36 bits for K7P803666M and 524,288 words by 18 bits for K7P801866M, fabricated using 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, 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 after addresses

and controls. The package is 119(7x17) Ball Grid Array with balls on a 1.27mm pitch.

Read Operation

During read operations, addresses and controls are registered during the first rising edge of K clock and then the internal array is

read between first and second edges of K clock. Data outputs are updated from output registers off the second rising edge of K clock.

During consecutive read operations 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 Operation(Late Write)

During write operations, addresses and controls are registered at the first rising edge of K clock and data inputs are registered at the

following rising edge of K clock. Write addresses and data inputs are stored in the data in registers until the next write operation, 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.

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 byte 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.

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, 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.

Mode Control

There are two mode control select pins (M

and M

) used to set the proper read protocol. This SRAM supports single clock pipelined

operating mode. For proper specified device operation, M

must be connected to V

and M

must be connected to V

. These

mode pins must be set at power-up and must not change during device operation.

Programmable Impedance Output Driver

The data output driver impedance is adjusted by an external resistor, RQ, connected between ZQ pin and V

, and is equal to RQ/5.

For example, 250Ω resistor will give an output impedance of 50Ω. 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

or V
