    Abstract: A data storage system and a global deduplication method thereof are provided. The data storage system includes multiple storage devices and one dispatch device. The dispatch device divides an original data corresponding to a data writing request into at least one data chunk. The dispatch device performs a summary calculation on one data chunk, so as to generate a representative value. The dispatch device performs a first distribution calculation on the representative value, so as to determine a destination location corresponding to the representative value. The dispatch device transmits the data chunk and the representative value to at least one destination storage device among the storage devices through a communication network according to the destination location. The at least one destination storage device checks the representative value, so as to determine whether to store the data chunk in a storage space of the at least one destination storage device.

    Abstract: A memory chip coupled to a host includes a memory and a controller. Multiple boot images having the same content are pre-loaded in the memory. The controller is coupled to the memory for processing data transmission between the memory chip and the host. The controller further determines whether the memory chip enters a boot mode for the first time. When the memory chip enters the boot mode for the first time, the controller accesses the memory so as to obtain a correct boot image from the boot images and transmits the correct boot image to the host.

    Abstract: A memory chip coupled to a host includes a memory and a controller. The memory is pre-loaded with a plurality of boot images, wherein the boot images have the same content. The controller is coupled to the memory, and processes data transmissions between the memory chip and the host, wherein the controller further determines whether the memory chip enters a boot mode for the first time, and when the memory chip enters the boot mode for the first time, the controller accesses the memory to obtain a correct boot image from the boot images and transmits the correct boot image to the host. Further, each boot image includes a plurality of data blocks, and the controller loads a plurality of correct data blocks from one or more of the boot images to obtain the correct boot image.

    Abstract: An overclocking process for a data storage device using a flash memory. A controller for the flash memory tests the flash memory using test clocks with various frequencies to determine at least one clock signal suitable to the flash memory. The clock candidates suitable to the flash memory are selected from the test clocks. The flash memory is operated in a variable-frequency manner by which the flash memory is switched between the clock candidates, such that electromagnetic interference is spread over different bands.

    Abstract: An identification technique for physically damaged blocks of a flash memory of a data storage device. In the data storage device, a controller coupled to the flash memory writes data into the flash memory with at least one time stamp corresponding to the data. The time stamp is taken into consideration by the controller to identify the physically damaged blocks of the flash memory, and thereby it is prevented from erroneously identifying a physically undamaged block as bad. Thus, the flash memory is prevented from being erroneously regarded as a write protected memory. The lifespan of the flash memory is effectively prolonged.
