Abstract
Memory apparatus for simultaneously transferring data between corresponding memory cells of two RAMs is disclosed. The two memories are fabricated on a common integrated circuit chip substrate with the corresponding memory cells of the two memories positioned adjacent one another and interconnected through a pair of transfer transistors. The transfer transistors as well as the power supply to each memory cell are controllable to cause the simultaneous copying of the data from the cells of one RAM into the corresponding cells of the other RAM.
