Abstract
Exemplary methods, apparatuses, and systems including an operation tracker for tracking operations of decks of a memory block. The operation tracker receives a command for a deck of a memory. The memory includes a plurality of separately accessible decks partitioned from a physical block of the memory. The operation tracker increments a read count for a deck of the plurality of separately accessible decks. Responsive to determining that the read count for the deck of the plurality of separately accessible decks satisfies a read count threshold, the operation tracker triggers a read disturb scan of the deck.
Claims20
A method comprising:
- receiving a command for a deck of a memory, wherein the memory comprises a plurality of separately accessible decks partitioned from a physical block of the memory;
- incrementing a read count for a deck of the plurality of separately accessible decks;
- and
- responsive to determining that the read count for the deck of the plurality of separately accessible decks satisfies a read count threshold, triggering a read disturb scan of the deck.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:
- receive a command for a deck of a memory, wherein the memory comprises a plurality of separately accessible decks partitioned from a physical block of the memory;
- increment a read count for a deck of the plurality of separately accessible decks;
- and
- responsive to determining that the read count for the deck of the plurality of separately accessible decks satisfies a read count threshold, trigger a read disturb scan of the deck.
A system comprising:
- a plurality of memory devices;
- and
- a processing device, operatively coupled with the plurality of memory devices, to:
- receive a command for a deck of a memory, wherein the memory comprises a plurality of separately accessible decks partitioned from a physical block of the memory, and wherein the command is one of a read command, an erase command, or a program verify command;
- increment a read count for a deck of the plurality of separately accessible decks;
- and
- responsive to determining that the read count for the deck of the plurality of separately accessible decks satisfies a read count threshold, trigger a read disturb scan of the deck.
