Abstract
Method and apparatus for securely erasing data from a non-volatile memory, such as but not limited to a flash memory array. In accordance with various embodiments, an extended data set to be sanitized from the memory is identified. The extended data set includes multiple copies of data having a common logical address and different physical addresses within the memory. The extended data set is sanitized in relation to a characterization of the data set. The data sanitizing operation results in the extended data set being purged from the memory and other previously stored data in the memory being retained.
