Description
The Intersil HS-65647RH is a fully asynchronous 8K x 8
radiation hardened static RAM. This RAM is fabricated using
the Intersil 1.2 micron silicon-on-sapphire CMOS technology.
This technology gives exceptional hardness to all types of
radiation, including neutron 鏗倁ence, total ionizing dose, high
intensity ionizing dose rates, and cosmic rays.
Low power operation is provided by a fully static design. Low
standby power can be achieved without pull-up resistors,
due to the gated input buffer design.
