Abstract

A system includes a memory device having memory cells and a processing device operatively coupled to the memory device. The processing device is to perform operations including: determining a length of time the memory device has been powered off; and in response to determining that the length of time satisfies a threshold value: for each of multiple groups of memory cells, asserting a corresponding flag; determining, based on the length of time, one or more adjusted demarcation voltages to be used in reading a state of the multiple groups of memory cells; and storing the one or more adjusted demarcation voltages for use in performing memory operations.
