64 BURST PIPELINED HIGH-SPEED
CMOS STATIC RAM
Publication Release Date: November 1998

Revision A1
GENERAL DESCRIPTION
The W25S243A is a high-speed, low-power, synchronous-burst pipelined, CMOS static RAM
organized as 65,536
×
64 bits that operates on a single 3.3-volt power supply. A built-in two-bit burst
address counter supports both Pentium
burst mode and linear burst mode. The mode to be
executed is controlled by the LBO pin. Pipelining or non-pipelining of the data outputs is controlled by
the FT pin. A snooze mode can reduces power dissipation.
This device supports 3-1-1-1-2-1-1-1 in a two-bank, back-to-back burst read cycle.
