ABSTRACT:
A virtual ground memory array where alternate bit lines in the array are selectively coupled to ground. The other bit lines are coupled to an input/output line. Diode-like shunting is used between the bit lines to eliminate parasitic paths particularly for higher programming potentials such as used in EPROMs. Substantially no increase in overhead is required to control these diode-like paths since the architecture allows them to be controlled by address signals.
