Abstract
A method according to one embodiment includes writing monitor data to at least one block of a memory device having finite endurance and/or retention; reading the monitor data after a period of time; determining a retention behavior of the at least one block based on the reading; and outputting a result of the determining. A memory device according to one embodiment includes a plurality of memory blocks having finite endurance and/or retention, at least one of the blocks having monitor data written therein; and circuitry for addressing the blocks. A system according to one embodiment includes a memory device having finite endurance and/or retention, the memory device comprising: a plurality of memory blocks, at least one of the blocks having monitor data written therein, wherein the at least one block has been written to a plurality of times prior to writing the monitor data; and circuitry for addressing the blocks.
