Abstract

Official abstract text for this publication.

In one embodiment, a memory system for writing redundant data output by an encoding processing circuit, comprises a memory, a encoding processing circuit, and a decoding circuit. The memory is electrically rewritable by using memory cells. The memory cells are capable of having two different resistance values corresponding to logical values of 1 or 0 respectively. The redundant data is read from and a predetermined logical value is written to the memory by flowing current in a same direction. The encoding processing circuit performs redundant encoding processing on target data and outputs redundant data. A number of bits having the predetermined logical value exceeds a number of bits having the logical value other than the predetermined logical value, for writing the redundant data to the memory. A decoding circuit reads data from the memory, and performs a decoding process on the data.
