High voltage generators having an integrated discharge path for use in non-volatile semiconductor memory devices

摘要

High voltage generators include a charge pump and a ripple reduction circuit that includes an integrated discharge path. The ripple reduction circuit limits the voltage level from a charge pump when the charge pump is in a first operating mode and provides a discharge path that from the output terminal of the ripple reduction circuit to the output of the charge pump when the charge pump is in a second operating mode. Semiconductor memories incorporating such high voltage generators are also provided. Coupling circuits having an integrated discharge path are also provided.
