    摘要: A method for fast chip erase of memory cells in a non-volatile memory array comprises the steps of providing an acceleration voltage greater than the internal pump voltage supplied by a conventional internal voltage supply pump, providing an erase write command, and performing a fast erase operation on the memory cells, comprising the step of coupling the acceleration voltage to the sources of the memory cells in a plurality of sectors simultaneously. In an embodiment, a fast preprogramming operation is performed on the memory cells prior to the step of performing the fast erase operation in the fast chip erase mode. In a further embodiment, a fast weak programming (APDE) operation is performed on the memory cells subsequent to the step of performing the fast erase operation in the fast chip erase mode. In an additional embodiment, the step of performing the fast erase operation further comprises the steps of detecting the acceleration voltage, generating an acceleration voltage indicator signal in response to the detection of the acceleration voltage, and generating a fast chip erase write command in response to the acceleration voltage indicator signal and the erase write command.
