Abstract
A communicating random access shared memory configuration for a multiprocessor system is connected to the processors for transferring data between the processors. The random access memory configuration includes a plurality of interconnected random access memory chips, each of these memory chips including first and second separate memory bit arrays having N word storage locations of M bit length with M bit buffer connected in between the first and second bit arrays on each memory chip, and first and second input/output ports connected to first and second bit arrays on each chip for entering and removing data externally to and from the chip. A controller is located on each chip and connected to the first and second memory arrays and the M bit buffer for transferring data between the first and second memory arrays and into and out of the first and second input/output ports.
