Abstract: A method for determining an optimal threshold of a nonvolatile memory device, the method including: reading a page from a nonvolatile memory device with a default threshold and attempting to hard decode the page using the default threshold; reading the page two more times with a predetermined offset voltage when the hard decoding fails and attempting to soft decode the page using the default threshold; approximating an empirical distribution of successfully decoded bits with a Gaussian distribution for each level; finding an intersection of the Gaussian distributions; and setting the intersection as a new reading threshold and reading the page again with the new reading threshold.

Abstract: Provided are a memory system, a method of reading data and a method of finding read thresholds. The method of finding read thresholds includes: selecting a channel distribution among a plurality of channel distributions that corresponds to a read page of the memory device to be read in response to a read command; generating a Trellis diagram based on a decoding scheme and a type of the read page; determining an optimal path through the Trellis diagram using the selected channel distribution according to a dynamic programming algorithm; and finding the read thresholds from the optimal path.
