Description
The HM-6561/883 is a 256 x 4 static CMOS RAM fabricated
using self-aligned silicon gate technology. Synchronous
circuit design techniques are employed to achieve high per-
formance 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 data inputs
and outputs are multiplexed internally for common I/O bus
compatibility.
The HM-6561/883 is a fully static RAM and may be
maintained in any state for an indefinite period of time. Data
retention supply voltage and supply current are guaranteed
over temperature.
