Radiation Hard 8192x8 Bit Static RAM
DS3692-7.0 January 2000
The MA9264 64k Static RAM is configured as 8192x8 bits and
manufactured using CMOS-SOS high performance, radiation hard,
1.5µm technology.
The design uses a 6 transistor cell and has full static operation with
no clock or timing strobe required. Address input buffers are deselected
when chip select is in the HIGH state.
See Application Note “Overview of the Dynex Semiconductor
Radiation Hard 1.5µm CMOS/SOS SRAM Range”.
