ABSTRACT:
The invention features a method of modifying a printed circuit board so that it can obtain a doubling of its integrated circuit capacity or memory storage. Identical integrated circuit chips are disposed in the same set of pin holes except for a select lead. The printed circuit is slightly modified to enable both chips to function independently. Thus, the density of the circuit board is increased, while using essentially the same circuitry and connections.
