Abstract
A method according to one embodiment includes gathering information about monitor data from a plurality of memory devices having finite endurance and/or retention, the monitor data being (i) data of known content stored in dedicated memory cells of known write cycle count, and (ii) write protected for preventing the monitor data from being overwritten with user data; analyzing the monitor data information; and taking an action relating to at least one of the devices based on the analyzing. Additional systems, methods, and computer program products are also disclosed.
Claims20
A method, comprising:
- gathering information about monitor data from a plurality of memory devices having finite endurance and/or retention, the monitor data being (i) data of known content stored in dedicated memory cells of known write cycle count, and (ii) write protected for preventing the monitor data from being overwritten with user data;
- analyzing the monitor data information;
- and
- taking an action relating to at least one of the devices based on the analyzing.
A method, comprising:
- gathering information about monitor data from a plurality of memory devices having finite endurance and/or retention, the monitor data being (i) data of known content stored in dedicated memory cells of known write cycle count, and (ii) not subject to wear leveling;
- analyzing the monitor data information;
- and
- taking an action relating to at least one of the devices based on the analyzing.
A system, comprising:
- a plurality of memory devices having finite endurance and/or retention, each of the memory devices having:
- 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, wherein the monitor data is at least one of:
- (i) data of known content stored in dedicated memory cells of known write cycle count, and (ii) write protected for preventing the monitor data from being overwritten with user data;
- and
- circuitry for addressing the blocks;
- a processor in communication with the memory devices, the processor being configured to gather information about the monitor data from the memory devices, analyze the information about the monitor data, and take an action relating to at least one of the devices based on the analyzing.
