Abstract
Systems, methods, and apparatuses are provided for drift compensation for codewords in memory. A memory device comprises memory cells and circuitry configured to sense a codeword stored in the array of memory cells using a reference voltage and determine an amount by which to adjust the reference voltage used to sense the codeword based on an estimated weight of the original codeword, a mean of threshold voltage values of each memory cell of the sensed codeword, and a total quantity of memory cells of the sensed codeword. The circuitry can further be configured to adjust the reference voltage used to sense the codeword by the determined amount.
