Abstract
Four parallel, spaced arrays of apertures are provided in a printed circuit (PC) board to accommodate mounting of 16- and 18-pin dynamic random access memories (DRAMs) within a minimum area footprint. First and second 8-aperture linear arrays are provided in the PC board in spaced relation to accommodate 16-pin DRAMs as are third and fourth 9-aperture linear arrays to accommodate 18-pin DRAMs, wherein the third and fourth arrays of apertures are aligned parallel with and respectively positioned intermediate and outside of the first and second arrays of apertures in the PC board. Corresponding apertures in the 16- and 18-aperture arrays for receiving corresponding pins of the 16- and 18- pin DRAMs are electrically coupled, with the two additional apertures of the 18-aperture array extending beyond the 16-aperture array and aligned therewith. The limited footprint area is thus capable of receiving, mounting and electrically coupling in circuit either a 16-pin or an 18-pin DRAM or any integrated circuit having a dual-in-line pinout configuration.
