  • Non-volatile memory (NVM) erase operation with brownout recovery technique
    Patent number: 8289773
    Abstract: A method for erasing a non-volatile memory includes: performing a first pre-erase program step on the non-volatile memory; determining that the non-volatile memory failed to program correctly during the first pre-erase program step; performing a first soft program step on the non-volatile memory in response to determining that the non-volatile memory failed to program correctly; determining that the non-volatile memory soft programmed correctly; performing a second pre-erase program step on the non-volatile memory in response to determining that the non-volatile memory soft programmed correctly during the first soft program step; and performing an erase step on the non-volatile memory. The method may be performed using a non-volatile memory controller.
