Abstract:
Disclosed is a system that comprises a memory device and a processing device, operatively coupled with the memory device, to perform operations that include, determining that a value of a write counter associated with the memory device satisfies a first threshold criterion, wherein the write counter is a global counter indicating a number of write operations to the memory device. The operations performed by the processing device further include determining that a set of failed bit count statistics corresponding to a plurality of codewords of a memory unit satisfies a second threshold criterion. The operations performed by the processing device further include, responsive to determining that the set of failed bit count statistics corresponding to the plurality of codewords of the memory unit satisfies the second threshold criterion, performing a write scrub operation on the memory unit.
