Abstract:
A system includes a memory device having a plurality of dice and A processing device to perform operations, including determining a representative number of program-erase cycles performed across the plurality of dice. The operations further include tracking the representative number of program-erase cycles over time. The operations further include, in response to the representative number of program-erase cycles satisfying a first threshold criterion, adding an additional threshold voltage offset bin to a plurality of threshold voltage offset bins for the memory device, wherein each of the plurality of threshold voltage offset bins comprises a corresponding window of time after program of data to the memory device.
