Preliminary W26L04A  
256K ´ 16 HIGH-SPEED CMOS STATIC RAM  
GENERAL DESCRIPTION  
´
The W26L04A is a high-speed, low-power CMOS static RAM organized as 262,144 16 bits that  
operates on a single 3.3-volt power supply.  
The W26L04A has an active low chip select, separate upper and lower byte selects, and a fast output
