A non-volatile transistor memory array, having individual cells, each individual cell having a current injector transistor and a non-volatile memory transistor. Injector current gives rise to charged particles that can be stored in the memory transistor by tunneling. When a row of the array is activated by a word line, the active row has current injectors ready to operate if program line voltages are appropriate to cause charge storage in a memory cell, while a cell in an adjacent row is erased by charge being driven from a memory transistor. A series of conductive plates are arranged in capacitive relation to the word line, with each plate having a pair of oppositely extending tangs, one allowing programming of a cell in a first row and another allowing erasing of a cell in another row.
