The UT67164 SRAM is a high performance, asynchronous, radiation-hardened, 8K x 8 random access memory conforming to industry-standard fit, form, and function. The UT67164 SRAM features fully static operation requiring no external clocks or timing strobes. UTMC designed and implemented the UT67164 using an advanced radiationhardened twin-well CMOS process. Advanced CMOS processing along with a device enable/disable function result in a high performance, power-saving SRAM. The combination of radiation-hardness, fast access time, and low power consumption make UT67164 ideal for high-speed systems designed for operation in radiation environments.
