The 54F189LLQB is a standard SRAM from Texas Instruments organized as 16 words by 4 bits, with a 32 ns access time. 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.
