256 x 4 CMOS RAM

Features

The HM-6551/883 is a 256 x 4 static CMOS RAM fabricated

using self-aligned silicon gate technology. Synchronous

circuit design techniques are employed to achieve high

performance and low power operation. On chip latches are

provided for address and data outputs allowing efficient

interfacing with microprocessor systems. The data output

buffers can be forced to a high impedance state for use in

expanded memory arrays.
