PREEMPTIVE READ REFRESH IN MEMORIES WITH TIME-VARYING ERROR RATES

Abstract:

A processing device in a memory sub-system determines a write-to-read delay time for a segment of a memory device read during a first read operation using a first read voltage level. The processing device further determines that the write-to-read delay time is associated with a second read voltage level and performs a read refresh operation on at least a portion of the segment of the memory device using the second read voltage level.
