ABSTRACT:
A random access memory device has memory cell blocks, row address decoders respectively associated with the memory cell blocks, sense amplifier circuit arrays each shared between two of the memory cell blocks, and a column selecting unit for transferring a data bit from one of the sense amplifier circuit arrays to an output data buffer circuit, a flag generating unit for producing flag signals indicative of memory cell blocks supplying the data bits presently stored in the sense amplifier circuit arrays, and an address discriminating unit operative to examine block and row addresses supplied from the outside thereof to see whether or not an accessed data bit has been already stored in the sense amplifier circuit arrays, thereby allowing the shared sense amplifier circuit arrays to serve as a cache memory.
