HM-6514/883
1024 x 4 CMOS RAM
Description
The HM-6514/883 is a 1024 x 4 static CMOS RAM fabri-
cated 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 eliminates
the need for pull up or pull down resistors. The HM-6514/883 is
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.
