Memory controller and method of controlling memory controller
Publication/Patent Number: US10635528B2 Publication Date: 2020-04-28 Application Number: 15/323,574 Filing Date: 2015-05-20 Inventor: Shinbashi tatsuo   Sakai, Lui   Ikegaya ryoji   Assignee: SONY CORPORATION   IPC: G11C29/52 Abstract: A utilization efficiency of a memory is improved. A codeword generation unit generates a codeword in an error detection and correction code from data to be encoded. A write control unit writes one of data obtained by inverting the codeword and the codeword into the memory cell as write data. A read data error correction unit reads out the write data from the memory cell as read data, and corrects an error in the read data. An inversion data error correction unit corrects an error in inversion data obtained by inverting the read data. A correction data output unit, when the number of errors of either only one of the read data and the inversion data does not exceed an error correction capability of the error detection and correction code, selects and outputs the one where the error is corrected as correction data.
