Abstract

A nonvolatile semiconductor memory cell array is shown which is composed of a plurality of unit cell-arrays arranged in a repeating pattern. Each of the unit cell-arrays includes a first plurality of cell transistors having control gates coupled in common to a first word line and a second plurality of cell transistors having control gates coupled in common to a second word line. The two word lines are arranged in parallel to one another and perpendicular to a bit line. The bit line is connected in common with drains of both the first and second plurality of cell transistors through a bit line contact. A pair of source lines is arranged along each side of the bit line and parallel to the bit line. Each source line is coupled to one transistor from each of the first and second pluralities of cell transistors through a source line contact.
