SELECTIVE SAMPLING OF A DATA UNIT BASED ON PROGRAM/ERASE EXECUTION TIME

Abstract:

A method includes obtaining a first operation execution time corresponding to an operation performed on a page of a first data unit of a memory device, determining whether the first operation execution time satisfies a condition that is based on a second operation execution time, wherein the second operation execution time is indicative of lack of defect in at least a second data unit of the memory device, and responsive to determining that the first operation execution time satisfies the condition that is based on the second operation execution time, initiating a defect scan operation of at least a subset of pages of the first data unit.
