Zusammenfassung:(1) Field of the Invention A multiple time programmable (MTP) memory device is achieved. The device comprises, first, a memory cell array including a means of electrical erasability and electrical programmability. The memory cell array comprises, preferably, a Flash memory cell array. A package has an external pin configuration that conforms to the JEDEC standard for an EPROM device wherein an external, positive programming voltage (VPP) pin is provided. Finally, an external, negative erasing voltage (VNN) pin is provided. The VNN pin is, preferably, multiplexed with the chip enable bar (CEB) pin.
