Abstract
A memory controller coupled to a memory device including an array of memory cells, each memory cell being set to one of 2states corresponding to a piece of N-bits data, where N is an integer greater than 1, and the array of memory cells being partitioned into one or more units. The memory controller is coupled to the memory device and configured to, upon executing instructions, obtain, from the memory device, a number P of memory cells in a unit of the units that are in one or more programmed states of the 2states; calculate, based on the number P, a compensated read voltage with an offset from a default read voltage; and provide, to the memory device, the compensated read voltage for a read operation performed on a selected memory cell of the memory cells in a unit of the units.
