Abstract
A solid state storage device is in communication with a host. The solid state storage device includes a control circuit and a non-volatile memory. The control circuit is in communication with the host. The control circuit includes an error correction circuit and a prediction model storage circuit. A prediction model is stored in the prediction model storage circuit. The non-volatile memory includes a memory cell array. The memory cell array includes plural blocks. Each of the blocks includes a corresponding state parameter. The control circuit determines a selected block from the memory cell array. The control circuit judges whether to perform a specified operation on the selected block according to the state parameter of the selected block and the prediction model.
