512K x 72 Synchronous Pipeline Burst ZBL SRAM
FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION
The WEDC SyncBurst - SRAM employs high-speed,
low-power CMOS design that is fabricated using an
advanced CMOS process. WEDC’s 32Mb SyncBurst
SRAMs integrate two 512K x 36 SSRAMs into a single
BGA package to provide 512K x 72 conguration. All
synchronous inputs pass through registers controlled by a
positive-edge-triggered single-clock input (CLK). The ZBL
or Zero 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.
