摘要:
A method of storing data into a memory array converts an input string into a first binary array with (m−1) rows and (n−1) columns. A second binary array with m rows and n columns in an encoded bit pattern is then generated from the first binary array. The second binary array in the encoded bit pattern has at most n/2 1's in each row and at most m/2 1's in each column, and the m-th row and an n-th column contain information for decoding other entries of the second binary array. The encoded bit pattern of the second binary array is then stored into corresponding memory devices of the memory array.

摘要:
A multi-state memory system with encoding that minimizes half-select currents. The system includes an array of row and column conductors with a plurality of storage cells each capable of being placed into any of three or more physical states. An encoder is connected to receive data bits for storage and to apply activation signals to the row and column conductors to write information to the storage cells. The encoder is programmed to encode the data bits into entries in an array having one row corresponding with each row conductor and one column corresponding with each column conductor; select entries in the array according to half-select currents of the storage cells; apply a predetermined one-dimensional mapping that increases the value of at most one entry in the array to obtain a mapped array; and write entries of the mapped array into the storage cells.

A data storage system including a memory array including a plurality of memory devices programmable in greater than two states. A memory control module may control operations of the memory array, and an encoder module may encode input data for storing to the memory array. The memory array may be an m×n memory array, and the memory control module may control operations of storing data to and retrieving data from the memory array.

A method and system for space-efficient error-control coding for encoding data into a 3-dimensional data-storage medium. The method and system enables the detection and correction of a bounded number of certain types of errors corresponding to the known failure modes of a class of 3-dimensional data-storage media.
摘要:
A system for memory word error correction that enables correction of burst errors in memory words. The system is based on an adaptation of two-error correction BCH code which yields burst error correction without increasing the number of error correction bits in the memory words over prior two-error BCH code error correction schemes. The adaptation of two-error correction BCH code when combined with additional techniques for detecting columns of burst errors enables the correction of burst errors and additional random bit errors in memory words.
