A dual port read/write register file memory includes means for performing a read/modify write cycle of operation within a single system cycle of operation. The register file memory is constructed from one to more (RAM) addressable multibit storage arrays organized to form a dual read port, single write port RAM. Additionally, the register file includes a plurality of clocked input registers arranged in pairs for storing command, address and data signals for two write ports. The different pairs of registers are connected as inputs to a first set of multip...


A dual port read/write memory having a single write input sort comprising: a random access memory (RAM) array having a plurality of addressable storage locations, said RAM having said single write port including a set of write data, address and write enable input terminals; clocked input register means for storing sets of write data, address and command information associated with a pair of ports; multiplexer selector means connected to said register means for receiving said sets of information and said multiplexer selector means being connected to apply...
