Description
The HM-6551/883 is a 256 x 4 static CMOS RAM fabricated
using self-aligned silicon gate technology. Synchronous cir-
cuit design techniques are employed to achieve high perfor-
mance 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.
The HM-6551/883 is a fully static RAM and may be main-
tained in any state for an indefinite period of time. Data
retention supply voltage and supply current are guaranteed
over temperature.
