Semiconductor memory with constant readout capability
 To extend the function of a bipolar type RAM, a register function is added to the RAM function. The register function is such that the contents stored in a memory cell is inputted to a differential switch, and the output to the differential switch is derived out to constantly read out the stored content of a desired bit with a simple circuit construction.
