Abstract
A method is described for performing a wipe-out and verification of a plurality of non-volatile memory (NVM) cells. The method includes performing an operation to set all the plurality of NVM cells to a single state. The single state may be one of a conducing or non-conducting state depending on the NVM architecture. After the operation to set the cells to the single state is complete, the verification is performed. In the verification operation, all cells of the plurality of NVM cells are set to the single state by performing a single read operation on the plurality of NVM cells. Detection of one of a conducting or non-conducting path through the plurality of NVM cells is used to verify if all cells of the NVM array had their contents wiped out. A notification is provided in response to all cells not being set to the single known state.
