White Electronic Designs Corp. reserves the right to change products or specications without notice.
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 conguration. All synchronous
inputs pass through registers controlled by a positive-
edge-triggered single-clock input (CK). 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 exibility for incoming signals.
