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 fluence, total ionizing dose, high intensity ionizing dose rates, and cosmic rays.
