ABSTRACT:
A nonvolatile memory cell that is highly scalable includes a cell formed in a triple well. A pair of sources for a pair of cells on adjacent word lines each acts as the emitter of a lateral bipolar transistor. The lateral bipolar transistor of one cell operates as a charge injector for the other cell. The charge injector provides carriers for substrate hot carrier injection onto a floating gate.
