Abstract
An array of rows and columns of memory cells of the virtual ground type employs a cell layout which has one column line per column instead of requiring extra lines for ground. Half of the column lines are used as outputs and half as ground. One output line and one ground line are selected by improved decode circuitry. The cell array is of a continuous web type wherein metal-to-silicon contacts are shared by four adjacent cells.
