    Abstract: An application specific integrated circuit (ASIC) tangibly encodes a program of instructions executable by the integrated circuit to perform a method for fast Chase decoding of generalized Reed-Solomon (GRS) codes. The method includes using outputs of a syndrome-based hard-decision (HD) algorithm to find an initial Groebner basis G for a solution module of a key equation, upon failure of HD decoding of a GRS codeword received by the ASIC from a communication channel; traversing a tree of error patterns on a plurality of unreliable coordinates to adjoin a next weak coordinate, where vertices of the tree of error patterns correspond to error patterns, and edges connect a parent error pattern to a child error pattern having exactly one additional non-zero value, to find a Groebner basis for each adjoining error location; and outputting an estimated transmitted codeword when a correct error vector has been found.

    Abstract: A method is provided for determining a deterioration condition of a memory device. The method includes calculating first information corresponding to a number of bits having a first logic value from data obtained by performing a first read operation on target storage region of the memory device using a first reference voltage as a read voltage, and calculating second information corresponding to a number of bits having a second logic value from data obtained by performing a second read operation on the target storage region using a second reference voltage as the read voltage. A deterioration condition of the target storage region is determined based on the first and second information. The first reference voltage is less than a first read voltage by which an erase state of the memory device is distinguished from an adjacent program state, and the second reference voltage is higher than the first read voltage.
