    Abstract: A technique for signal deskew at the non-volatile memory side. The non-volatile memory includes a plurality of dies and a signal timing adjustment circuit. The dies are grouped into storage zones. A controller is coupled to the non-volatile memory through a plurality of data lines. Through the data lines, the controller issues a plurality of commands to provide zone delay parameters to the non-volatile memory to drive the signal timing adjustment circuit at the non-volatile memory side to separately adjust data-line timing of the different storage zones.

    Abstract: A method of a flash controller to be coupled between a flash memory device and a host device is provided. The flash memory device has a plurality of blocks each having a plurality of pages, and the method comprises: receiving a trim/erase/unmap command from the host device; obtaining a storage space, which is to be erased, from the trim/erase/unmap command; comparing a space size of the storage space with a threshold to determine whether the space size is larger than the threshold; and resetting valid page counts of the plurality of blocks of the flash memory device when the space size is larger than the threshold.

    IPC: G06F3/06

    Abstract: A method of a flash memory controller connected to a flash memory includes: receiving a data unit from the host via a bust of the host; controlling the flash memory to load a full page data from the flash memory into a buffer of the flash memory; and writing the data unit into the buffer to update or replace a portion data of the full page data stored in the buffer, to control the flash memory write the full page data which has been updated by the data unit from the buffer into the flash memory.

    Abstract: A method for moving data internally, performed by a processing unit, including at least the following steps. The processing unit transmits partial copyback read commands to a storage sub-unit through an access interface, where each partial copyback read command is used to direct logic circuits of the storage sub-unit to store partial data of a page of the storage sub-unit in a designated location of a data buffer of the storage sub-unit. The processing unit further transmits a copyback write command to the storage sub-unit through the storage sub-unit for programming the data of the data buffer in a new page of the storage sub-unit.

    Abstract: A flash memory controller includes a read/write unit, a state machine, a processing unit, and an auxiliary unit. The read/write unit is connected to a flash memory and performs a writing command or a reading command. The state machine is configured to determine a state of the flash memory controller. The processing unit is connected to the read/write unit and the state machine and configured to control the read/write unit. The auxiliary unit is connected to a first data line and a second data line and the processing unit and configured to receive and store a string output from the processing unit. The auxiliary unit outputs the string through the first and second data lines when the flash memory controller completes a writing data transmission.

    Abstract: The invention provides a flash memory device. In one embodiment, the flash memory device is coupled to a host, and comprises a flash memory, a controller, and a random access memory. The flash memory comprises a plurality of blocks for data storage. The random access memory stores a read count table for recording read counts of the blocks. When the read counts of a plurality of original blocks are greater than a threshold according to the read count table, the controller obtains a plurality of spare blocks from the flash memory as mirror blocks respectively corresponding to the original blocks, and copies a portion of a plurality of data pages of the original blocks to the mirror blocks whenever the original blocks are read until all of the data pages of the original blocks have been copied to the mirror blocks.
