General Description
The UM6104 is a 1024x4 fu IIy stat ic CMOS. RAM. The
device utilizes synchronous circuitry to achieve perform-
ance and low power operation.
Pin Configuration
Block Diagram
On chip latches are provided for the addresses allowing
efficient interfacing with microprocessor systems. The data
output can be forced to a high impedance state for use in
expanded memory systems.
