Abstract
A data processing method for a solid state drive is provided. The solid state drive includes a control circuit and a non-volatile memory. The control circuit includes a logical-to-physical table. The non-volatile memory includes plural blocks. When a data area of a data block is fully occupied with a write data, a block-closing action is performed on the data block. After the block-closing action is completed, a close information corresponding to the data block is stored into an information area of the data block and the data block is recognized as a used block. When a trim command is received, the control circuit judges whether the used block is changed to an unused block according to the trim command. If the used block is changed to the unused block, the close information is stored into a trim block.
