Abstract

A memory with controlled gate current injection during memory cell programming wherein programming circuitry applies a time-varying voltage to a control gate of the memory cell during a programming cycle. The time-varying voltage yields a substantially constant rate of electron flow from the channel region to the floating gate during the programming cycle.
