n Fast access times: 2$8, 3$0, 3$5 and 3$8ns  
n Fast OE access times: 2$8, 3$0, 3$5 and 3$8ns  
n Separate Core and I/O Power Supply  
n Snooze Mode for reduced-standby power  
n Individual Byte Write control  
The WEDC SyncBurst - SRAM family employs high-  
speed, low-power CMOS designs that are fabricated  
using an advanced CMOS process$ WEDC’s 72Mb  
SyncBurst SRAMs integrate two 2M x 18 SRAMs into a  
single BGA package to provide a 2M x 36 configuration$  
All synchronous inputs pass through registers con-  
trolled 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$” Asynchronous inputs include the sleep mode en-  
able (ZZ) and Output Enable (OE)$ Write cycles are in-  
ternally 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$  
n Clock-controlled and registered addresses, data I/Os  
and control signals  
n Burst control (interleaved or linear burst)  
n Packaging:  
• 119-bump BGA package, JEDEC Pin Definition  
n Low capacitive bus loading
