| Abstract(in English) | NAND flash memories have lifetime such as data-retention time and read cycles. This paper proposes neural network technique to predict lifetime of NAND flash memories. In addition, this paper proposes a method to correct cell errors of NAND flash memories. Neural network learns dependence of cell errors and can detect errors. The detected error bits are flipped and corrected. As a result, this method improves the reliability of 3D NAND flash memory. During pre-shipment test in fabs, lifetime of NAND flash memories is predicted. Based on the lifetime, NAND flash chips are sorted. Optimal chips are shipped to markets such as archives where chips with long data-retention lifetime are required and markets where data is read frequently, respectively. |
