Abstract
A computer-implemented method according to one embodiment includes determining, after writing data to a non-volatile memory block, one or more delta threshold voltage shift (TVS) values. One or more overall threshold voltage shift values for the data written to the non-volatile memory block are calculated, the values being a function of the one or more TVSvalues to be used when writing data to the non-volatile memory block. The overall threshold voltage shift values are stored. A base threshold voltage shift (TVS) value, the one or more TVSvalues, or both the TVSvalue and the one or more TVSvalues are re-calibrated during a background health check after a predetermined number of background health checks without calibration are performed.
