Abstract
The various implementations described herein include systems, methods, and/or devices used to selectively throttle host reads in memory devices. The method includes: (1) identifying a storage location in the non-volatile memory system with high read disturbs vulnerable to reliability issues, (2) determining if the identified storage location is being throttled for host reads, (3) in accordance with a determination that the identified storage location does not satisfy the predefined read throttling criteria, initiate execution of a read operation, otherwise, enqueue read commands for deferred execution.
