Selective data corruption before actual erase operation for data security

Abstract

In some implementations, a controller may receive a command to perform an erase operation to erase data stored in a block of a non-volatile memory device. The controller may determine a size of the data identified by the command. The controller may provide, based on the size of the data, a programming pulse to a location, of the block, that stores the data, wherein the programming pulse is provided to write predetermined data at the location. The controller may perform an erase operation on the block after writing the predetermined data.
