Abstract
Apparatus and method for managing data in a memory, such as but not limited to a flash memory array. In some embodiments, an apparatus includes an array of memory cells and a dual polarity charge pump. The dual polarity charge pump has a positive polarity voltage source which applies a positive voltage to a charge storage device to program a selected memory cell to a first programming state, and a negative polarity voltage source which applies a negative voltage to the charge storage device to program the selected memory cell to a different, second programming state.
