Abstract
A solution for deteriorated non-volatile memory is shown. When a controller determines that raw data read from the non-volatile memory is undesirable data, the controller performs safety moving of valid data of an erasure unit that contains the raw data to safely move the valid data of the erasure unit, wherein the erasure unit is a high-risk block, and the raw data in the non-volatile memory is regarded as being in a deteriorated physical address. Prior to being moved in the safety moving, the raw data is changed so that it is different from the undesirable data. In an exemplary embodiment, the undesirable data is all-1's data or all-0's data.
