INTRODUCTION
The UT7C138 and UT7C139 are high-speed radiationhardened CMOS 4K x 8 and 4K x 9 dual-port static RAMs. Arbitration schemes are included on the UT7C138/139 to handle situations when multiple processors access the same memory location. Two ports provide independent, asynchronous access for reads and writes to any location in memory.
FEATURES
? 45ns and 55ns maximum address access time
? Asynchronous operation for compatibility with industry
standard 4K x 8/9 dual-port static RAM
