Abstract
A memory device to perform a calibration of read voltages of a group of memory cells. For example, the memory device can measure signal and noise characteristics of a group of memory cells to determine an optimized read voltage of the group of memory cells and determine an amount of accumulated storage charge loss in the group of memory cells. Subsequently, the memory device can perform a read voltage calibration based on the determined amount of accumulated storage charge loss and a look up table.
