Abstract
A high-density storage system includes a memory device, and a controller including a range allocation and program order block configured to determine a range of a threshold voltage for each level of each memory cell of the memory device, based on initial data and an interference in the memory device, and determine an order in which groups of memory cells of the memory device are programmed, based on the interference. The controller further includes a statistical cell correction block configured to perform statistical cell correction on the range of the threshold voltage for each level of each memory cell, based on the order in which the groups of the memory cells are programmed and reference information of each level of each memory cell of the memory device that is received from the memory device.
