General Description
The UMC UM6167 is a 16,384 bit static random access
memory organized as 16,384 words by 1 bit and operates
from a single 5 volt supply. It is built with UMC's high
performance twin tub CMOS process. Inputs and three-
state outputs are TTL compatible. The UM6167 is moulded
in a standard 20-pin, 300 mil DIP.
