GENERAL DESCRIPTION
The Micron
®
SyncBurst
™
SRAM family employs
high-speed, low-power CMOS designs that are fabri-
cated using an advanced CMOS process.
Micron’s 8Mb SyncBurst SRAMs integrate a 512K x
18, 256K x 32, or 256K x 36 SRAM core with advanced
synchronous peripheral circuitry and a 2-bit burst
counter. All synchronous inputs pass through registers
controlled by a positive-edge-triggered single-clock in-
put (CLK). The synchronous inputs include all ad-
dresses, all data inputs, active LOW chip enable (CE#),
two additional chip enables for easy depth expansion
(CE2#, CE2), burst control inputs (ADSC#, ADSP#,
