In each of multiple logic cells of a Programmable Gate Array ("PGA"), a programing array is provided having multiple programming words therein. Each of the programming words is engagable to control the configuration of the logic cell. The programming words are selectively engaged such that multiple functions are performed by the logic cell within the PGA. As a result, a PGA with a number of virtual logic cells in excess of actual physical logic cells is provided. The PGA therefore has the capability to emulate a PGA with a larger number of logic cells than it physically has.
