Zusammenfassung:A non-volatile memory device includes: a plurality of memory cells (18) and a charge pump (24) coupled with the memory cells. The charge pump can be dynamically reconfigured to provide a first voltage to the memory cells in the bypass mode, provide a first voltage to the memory cells in the program mode, and provide a second voltage which has an opposite polarity to the first voltage in the erase mode.
