RAM with bit addressing - has eight memory stages for bit storage individually accessed by decoded three bit address

摘要

A v.a.m. for use in microprocessor applicators allows multi-bit words to ba addressed on a bit basis. The system utilises eight single memory modules, each containing a number of single bit locations addressed by ten bits supplied from a common bus. The outputs of the memory are coupled onto an 8 bit data bus over a coupling stage. The addresses for the memory locations are provided on one section of an address register. A separate section of the register contains a three bit address that is decoded and gated to identify the specific memory bit store to be accessed.
