Claim:
1. A method to control a memory system that includes memory blocks, wherein each memory block has memory pages, and each memory page has memory cells, the method to control the memory system comprising: determining one or more memory pages to be analyzed; identifying read threshold voltages of each memory cell associated with the determined one or more memory pages to be analyzed; calculating a read disturb count for a respective one of the determined one or more memory pages, wherein the identified read threshold voltages are associated with the read disturb count; performing statistical analysis on the identified read threshold voltages associated with the read disturb count; determining a distribution of the identified read threshold voltages associated with the read disturb count based, at least in part, on the statistical analysis; and decoding data written on at least one memory page of the memory system based, at least in part, on the determined distribution of the identified read threshold voltages.
