This is a very small, fast memory block — think register file, cache tag store, or a small look-up table in a glue-logic bank, not a main memory array. It uses CMOS technology, which keeps standby current low compared to bipolar SRAMs of the same era.","metaTitle":"54F189LLQB Texas Instruments 16x4 SRAM 32ns Active","metaDescription":"Texas Instruments 54F189LLQB standard SRAM, 16x4 organization, 32 ns access time, CMOS, Bulk package.
