DESCRIPTION

The 8 Meg 'NP' product family feature high-speed,

low-power synchronous static RAMs designed to provide

a burstable, high-performance, 'no wait' state, device for

network and communications customers. They are

organized as 262,144 words by 32 bits, 262,144 words

by 36 bits and 524,288 words by 18 bits, fabricated with

ISSI

's advanced CMOS technology.

Incorporating a 'no wait' state feature, wait cycles are

eliminated when the bus switches from read to write, or

write to read. This device integrates a 2-bit burst counter,

high-speed SRAM core, and high-drive capability outputs

into a single monolithic circuit.

All synchronous inputs pass through registers are controlled

by a positive-edge-triggered single clock input. Operations

may be suspended and all synchronous inputs ignored

when Clock Enable,

CKE

is HIGH. In this state the internal

device will hold their previous values.

All Read, Write and Deselect cycles are initiated by the

ADV input. When the ADV is HIGH the internal burst

counter is incremented. New external addresses can be

loaded when ADV is LOW.

Write cycles are internally self-timed and are initiated by

the rising edge of the clock inputs and when

is LOW.

Separate byte enables allow individual bytes to be written.

A burst mode pin (MODE) defines the order of the burst

sequence. When tied HIGH, the interleaved burst sequence

is selected. When tied LOW, the linear burst sequence is

selected.
