ABSTRACT:
A dual port memory has been provided which allows read and write operations by separate data processors during a read cycle of one of the processors. A method of accomplishing this is provided by shortening the column drive signal to disconnect the column line from the sense amplifier once the sense amplifier has latched the data being read. Write circuitry can then be enabled to write into the memory cell which has just been read by the sense amplifier.
