摘要： The present invention disclosed herein is a high voltage generator circuit. The high voltage generator circuit includes a charge pump and a pump clock signal generator. The pump clock signal is gated to the charge pump when the high voltage is below a target voltage. After the high voltage reaches the target voltage, the high voltage cyclically falls below the target voltage. After the high voltage reaches the target voltage, a pump clock generator block circuit limits the transmission of the pump clock signal so that only N clock signals are gate to the charge pump each cycle, where N is the number one or greater.

摘要： A non-volatile memory device and a bad block remapping method use some of main blocks as remapping blocks to replace a bad block in a main cell block and selects remapping blocks using existing block address signals. Thus, separate bussing of remapping block address signals is not needed. The bad block remapping includes comparing an external block address input from an external source to a stored bad block address, generating a bad block flag signal when the external block address is identical to the stored bad block address, generating a remapping block address selecting the remapping blocks in response to a remapping address corresponding to the bad block address, selecting one of the external block address and the remapping block address in response to the bad block flag signal to create a selected address, and outputting a row address signal in accordance with the selected address.
