Abstract(in English) | The cost of NAND flash memory is reduced by scaling and multi-level cell technologies. However, the reliability of triple-level cell (TLC : 3-bit/cell) NAND flash is degraded due to the narrower read margins. Moreover, due to the write/erase endurance stress, traps which may capture electrons are generated in the tunnel oxide. Data-retention error is caused by ejecting electrons from the floating-gate via traps. Reliability is degraded by scaling since the threshold voltage is more decreased when one electron ejects. This paper reports data-retention error reduction technique of TLC NAND flash memory. |
