ABSTRACT:
A system (10) and method for providing simultaneous data reading and writing for a random access memory (18) include storing new data (14) and a corresponding new data address (26), comparing the new data address to a current read address (32), and substituting (38) the new data for the data at the current read address at the output (38) while simultaneously writing the new data into the memory (18). The system and method are particularly suited for application in space-based communication satellites which utilize continuous memory read accesses since the invention provides the functionality of a dual-ported RAM while being implementable with fewer gates and less complex control circuitry to provide reduced power consumption.
