Abstract
An electrically erasable non-volatile memory cell dissipates virtually no power by disabling a pull-up current when the non-volatile memory cell is programmed. In one embodiment, to properly initialize the electrically erasable non-volatile memory cell, the power of an inverting output buffer is provided only after the pull-up circuit substantially completes pulling up an input terminal of the inverting output buffer. In one embodiment, the electrically erasable non-volatile memory cell is used in a programmable integrated circuit.
