Patent ID: 8279668

Claim:
A method of operation for a non-volatile memory, the non-volatile memory including a physical page including a set of multi-bit memory cells connected to a word line, each memory cell having an adjustable threshold voltage, the physical page including a first portion and a second portion, the method comprising: programming the first portion of the physical page and the second portion of the physical page; then, reading the first portion of the physical page and the second portion of the physical page using a first set of read verify reference voltages to analyze the threshold voltages of the memory cells; then, obtaining first information in response to reading the second portion of the physical page, the first information including information regarding a change of threshold voltages of at least some of the memory cells; then, determining a second set of read verify reference voltages based on the first information; and then, reading the first portion of the physical page using the second set of read verify reference voltages.
