Abstract: A controlling method for a solid state drive is provided. The solid state drive includes a controlling circuit and a resistive random-access memory. Firstly, a monitor factor is defined. The monitor factor is associated with a life span of the resistive random-access memory. If the monitor factor is higher than a predetermined value, a mapping algorithm of a logical-to-physical table is established by the controlling circuit and a logical block address of a host is mapped to a physical allocation address by the controlling circuit according to the logical-to-physical table, and a data accessing action is performed.

Abstract: A controlling method is provided for preventing a solid state drive from being operated at a high temperature. The solid state drive includes a controlling circuit, a temperature detecting circuit and a plurality of dies. The dies are divided into n groups and accessed by the controlling circuit through n IO buses. The controlling circuit is in communication with the temperature detecting circuit for detecting a temperature of the solid state drive. The controlling method includes the following steps. Firstly, a judging step is performed to judge whether the temperature of the solid state drive is higher than a predetermined temperature. If the temperature of the solid state drive is higher than the predetermined temperature, the frequencies of n clock signals in the n IO buses are decreased.

Abstract: A flash storage device comprises: a memory module, for storing data; a control unit, electrically connected to the memory module, for accessing the data in the memory module; and a detecting unit, electrically connected to the control unit, for passing a temperature detecting result to the control unit, and the control unit determining whether a data protection operation is activated according to the temperature detecting result.

Abstract: A solid state drive includes a flash memory and a controlling unit. The flash memory includes plural blocks. Each block includes plural pages. The controlling unit is in communication with the flash memory. When data of a specified block are erased or data are written into the specified block, the controlling unit provides a time parameter to the specified block. The controlling unit performs a data loss prevention, a wear leveling operation or a garbage collection according to the time parameter.

Abstract: A method of wear leveling applied to a non-volatile memory is provided. The method comprises steps of: categorizing all blocks within the non-volatile memory to a first group with erased blocks having higher history numbers, a second group with erased blocks having lower history numbers, or a third group with blocks not either assigned to the first group or the second group; selecting a first block which contains a clod data from the third group; selecting a second block from the first group; copying the cold data from the first block into the second block and updating the history number of the second block; and erasing the first block.

Abstract: A method for arranging conducting lines of a flexible cable in an optical disk drive first confirms the pins having similar functions of all chips on a main board and a sub-board, and uses only one conducting line of the flexible cable to connect these pins. Therefore, the number of the conducting lines of the flexible cable can be reduced.
