Abstract: HIGH MEMORY DENSITY PACKAGE Disclosed is a high density microelectronic circuit package. The circuit package includes a plurality of IC chips, as memory chips, on a circuitized flexible tape, which is, in turn, bonded to a printed circuit board. The circuitized flexible tape extends outwardly from the printed circuit board and has a plurality of IC chips mounted on I/O pads on the tape. The individual IC chips are in thermal contact with a heat sink means on the surfaces thereof opposite the circuitized flexible tape. The circuitized flexible tape and the heat sink are bonded to a printed circuit board.
