| Abstract(in English) | Flash memories are used in many ways, because of the features of fast random access speed, power consumption, and resistance to physical shocks. In recent years, multilevel cell (MLC) flash memories that store multiple data bits in a memory cell are introduced for the high density integration. In MLC flash memories, the level of charge is apt to change to neighboring level by charge fluctuations. Especially, 1 level fluctuations are apt to occur extremely frequently. This paper proposes 1 level error correcting code suitable for MLC flash memories in order to control errors efficiently. The proposed method utilizes an asymmetric error locating code and a mapping derived from Gray codes. Evaluation shows that the code length of the proposed code is larger than that of conventional codes. |
