Abstract:
A multiple polarity reversible charge pump circuit is disclosed which, in certain embodiments, may be configured to generate a positive voltage at times and may be reversed to generate a negative voltage at other times. Such a charge pump circuit is advantageous if both the positive and negative voltage are not simultaneously required. In certain other embodiments, a charge pump circuit generates a high output current for only a positive boosted voltage in one mode of operation, but lower current positive and negative boosted voltage outputs in another mode of operation. Use with certain erasable memory array technologies is disclosed, particularly certain resistive passive element memory cells, and more particularly in a three-dimensional memory array.
