Abstract:
A processing device, operatively coupled with a memory device, performs operations including receiving a write request from a host system at a first time, the write request identifying first data to be stored in a segment of the memory device, determining whether a pre-read voltage level of the write request satisfies a pre-read voltage level criterion pertaining to a write-to-write time interval for the segment, wherein the write-to-write time interval is defined by the first time and a second time corresponding to a last time at which the segment was written, and responsive to determining that the pre-read voltage level satisfies the pre-read voltage level criterion pertaining to the write-to-write time interval, performing a pre-read operation on the segment using the pre-read voltage level to determine second data currently stored in the segment.
