| Abstract(in English) | Non-volatile memory has many advantages over SRAM, such as high density, low leakage power, and non-volatility. However, one of its largest problems is that it consumes a large amount of energy in writing. It is quite necessary to reduce the number of writing bits and thus decrease its writing energy. In this paper, we propose a memory writing reduction method based on state encoding limiting maximum Hamming distance. When a data is written into a memory, we do not write it directly but encode it into a codeword. Then we write the codeword into a memory. At this time, we encode a data into a codeword limiting its maximum Hamming distance from another codeword. If the maximum Hamming distance is limited among all the codewords, the number of flipped bits are also limited and then the number of writing bits will be reduced. We show several experimental evaluations and discuss the effectiveness of our proposed algorithm. |
