Abstract

A device for increasing the density of integrated circuit chips on a printed circuit board. A plurality of integrated circuits are packaged within chip carriers and stacked, on one top of the other, on a printed circuit board. Each of the input/output data terminals, power and ground terminals of the chips are connected in parallel. Each chip is individually accessed by selectively enabling the desired chip.
