DESCRIPTION
The WEDC SyncBurst - SRAM famly employs high-speed, low-
power CMOS designs that are fabricated using an advanced CMOS
process. WEDC’s 16Mb SyncBurst SRAMs integrate two 512K x 16
SRAMs into a single BGA package to provide 512K x 32 configura-
tion. All synchronous inputs pass through registers controlled by a
positive-edge-triggered single-clock input (CLK). The synchronous
inputs include all addresses, all data inputs, active LOW chip enable
(CE), burst control input (ADSC) and byte write enables (BW
0-3
).
Asynchronous inputs include the output enable (OE), clock (CLK)
and snooze enable (ZZ). There is also a burst mode input (MODE)
that selects between interleaved and linear burst modes. Write cycles
can be fromone to four bytes wide, as controlled by the write control
inputs. Burst operation can be initiated with the address status
controller (ADSC) input.
