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 2Mb SyncBurst SRAMs integrate a 128K x

18, 64K x 32, or 64K 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

input (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#,

ADV#), byte write enables (BWx#) and global write

(GW#).

Asynchronous inputs include the output enable

(OE#), snooze enable (ZZ) and clock (CLK). There is also

a burst mode pin (MODE) that selects between inter-

leaved and linear burst modes. The data-out (Q), en-

abled by OE#, is also asynchronous. WRITE cycles can

be from one to two bytes wide (x18) or from one to four

bytes wide (x32/x36), as controlled by the write control

inputs.

Burst operation can be initiated with either address

status processor (ADSP#) or address status controller

(ADSC#) input pins. Subsequent burst addresses can be

internally generated as controlled by the burst advance

pin (ADV#).
