The HM-6561/883 is a 256 x 4 static CMOS RAM fabricatedusing self-aligned silicon gate technology. Synchronous circuit design techniques are employed to achieve high performanceand low power operation.On-chip latches are provided for address and data outputsallowing efficient interfacing with microprocessor systems.The data output buffers can be forced to a high impedancestate for use in expanded memory arrays. The data inputs andoutputs are multiplexed internally for common I/O bus compatibility.The HM-6561/883 is a fully static RAM and may bemaintained in any state for an indefinite period of time. Data retention supply voltage and supply current are guaranteedover temperature.
