16 HIGH-SPEED CMOS STATIC RAM
GENERAL DESCRIPTION
The W26020A is a high-speed, low-power CMOS static RAM organized as 131,072
×
16 bits that
operates on a single 5-volt power supply. This device is manufactured using Winbond's high
performance CMOS technology.
The W26020A has an active low chip select, separate upper and lower byte selects, and a fast output
enable. No clock or refreshing is required. Separate byte select controls (
LB
and
UB
) allow
individual bytes to be written and read.
LB
controls I/O1-I/O8, the lower byte.
UB
controls I/O9
I/O16, the upper byte. This device is well suited for use in high-density, high-speed system
applications.
