Abstract
A system includes a memory device and a processing device, operatively coupled to the memory device. In some embodiments, the processing device accesses a matrix of threshold voltage offset bins, where a first dimension of the matrix is temperature and a second dimension of the matrix is a temporal voltage shift (TVS) amount. The processing device measures a temperature value based on a reference temperature value for a block family. The processing device measures a TVS value of a voltage level within one or more memory cell of the block family. The processing device retrieves, from the matrix, a threshold voltage offset bin based on the reference temperature value and the TVS value and reads data from any page of the block family via application of a threshold voltage offset, specified by the threshold voltage offset bin, to a base read level voltage.
