Abstract

A read only memory integrated semiconductor device includes at least one memory cell. The memory cell includes a storage transistor made within a semiconductor substrate and whose source is connected to ground. A word line is connected to the gate of the transistor. Only one of several bit lines may be connected to the drain of the transistor at a time.
