Abstract

A memory system or a method for estimating channel information to be used for error decoding. The memory system or the method a) performs one or more read operations on a page selected from among the plurality of pages using a target read threshold, b) obtains the target read threshold, a historical read threshold voltage set associated with failed read operations of the selected page, checksum values, and asymmetric ratios of ones count and zeros count which are associated with the historical read threshold voltage set, c) provides the obtained target read threshold, historical read threshold voltage set, checksum values and asymmetric ratios as input information to a neural network, and d) predicts, by the neural network, channel information at the target read threshold based on the input information and a set activation function.
