UT7C139, UT7C138, (UT7C138 / UT7C139) 4Kx8/9 Radiation-Hardened Dual-Port Static RAM

3 The UT7C138/139 consists of an array of 4K words of 8 or 9 bits of dual-port SRAM cells, I/O and address lines, and control signals (CE, OE, R/W).

These control pins permit independent access for reads or writes to any location in memory.

To handle simultaneous writes/reads to the same location,
