Description
The HM-6514 is a 1024 x 4 static CMOS RAM fabricated
using self-aligned silicon gate technology. The device utilizes
synchronous circuitry to achieve high performance and low
power operation.
On-chip latches are provided for addresses allowing efficient
interfacing with microprocessor systems. The data output
can be forced to a high impedance state for use in expanded
memory arrays.
Gated inputs allow lower operating current and also elimi-
nate the need for pull up or pull down resistors. The
HM-6514 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 guaran-
teed over temperature.
