DESCRIPTION

The WEDC SyncBurst — SRAM family employs high-

speed, low-power CMOS designs that are fabricated

using an advanced CMOS process. WEDC’s 32Mb

SyncBurst SRAMs integrate two 1M x 18 SRAMs into a

single BGA package to provide 1M x 36 configuration. All

synchronous inputs pass through registers controlled by

a positive-edge-triggered single-clock input (CLK). The

NBL or No Bus Latency Memory utilizes all the bandwidth

in any combination of operating cycles. Address, data

inputs, and all control signals except output enable and

linear burst order are synchronized to input clock. Burst

order control must be tied “High or Low.” Asynchronous

inputs include the sleep mode enable (ZZ). Output Enable

controls the outputs at any given time. Write cycles are

internally self-timed and initiated by the rising edge of the

clock input. This feature eliminates complex off-chip write

pulse generation and provides increased timing flexibility

for incoming signals.
