Abstract

A decoding circuit is coupled to the signal lines that communicate address signals to a memory unit. When a predetermined address is communicated, the decoding circuit produces a supplemental signal that is coupled to the memory unit and used to select one of a plurality of groups of memory locations. The communicated address signals specify the memory location of the selected group to be accessed.
