IPC: G11C16/06
Filed: 2002-02-21
Abstract: PROBLEM TO BE SOLVED: To perform surely error detecting/correcting of a multi-level semiconductor memory with a simple means. SOLUTION: Binary bit addresses for detecting an error corresponding respectively to addresses indicating each bit of multi-level memory cells holding binary bits data are allotted so that each figure of two binary bits addresses corresponding to one memory cell is made exclusive. For each figure of binary bits addresses, parity codes of data corresponding to all binary bit addresses of which the figure is '0' and parity codes of data corresponding to all binary bit addresses of which the figure is '1' are generated respectively for write-in data and read-out data. When a first parity code of read-out data is different from a first parity code of write-in data, it is found that one memory cell in which two bits data are both errors exists.
