In a caching method implemented by a data storage system, a data word as user data is encoded into a codeword that is then written into an area of a cache memory. The codeword includes a data portion, a checksum parity portion and an error correction code (ECC) parity portion. In response to a read request for the user data, the codeword read from the cache memory is decoded based on the ECC parity portion to correct one or more bit errors within the data portion so as to generate a read data portion and a read checksum parity portion. Upon identifying that a validating checksum portion generated based on the read data portion matches the read checksum parity portion, the read data portion serving as the user data is outputted. Otherwise, a data storage unit outputs the user data previously stored therein.

Caching method and data storage system capable of prolonging service lifetime of a cache memory

An operating method of a storage device is provided. The operating method comprises the following steps. First, a first data is read from a target address of a first storage unit. Then, an assisting unit checks whether the target address is corresponding to a second data stored in a second storage unit. If the target address is corresponding to the second data, the assisting unit updates the first data according to the second data to generate an updated data. Next, an Error Correction Code (ECC) performs a decoding process on the updated data to generate a decoded data.

Storage device and operating method thereof

The present disclosure relates, according to some embodiments, to a data writing method in a storage system. The method comprises receiving data by the storage media controller, reading a non-volatile memory operation mode in the memory unit by a central control unit, in which the mode corresponds to a data reliability lower than the data reliability requirement of the storage system, reading a data reliability reduction condition in the memory unit by the central control unit, determining whether a system information related to the data meets the condition by the central control unit, and controlling the media control unit to write the data into the non-volatile memory according to the mode by the central control unit when the system information meets the condition.

Flash memory storage system and access method

A method for operating a memory includes receiving a command to program a data value at a memory cell, and an indication of which write mode in a plurality of write modes to use. Write modes in the plurality are characterized by different sets of resistance ranges that correspond to data values stored in the memory cell. The method includes executing a program operation according to the indicated one in the plurality of write modes to program the data value in the memory cell. The plurality of write modes includes a first write mode and a second write mode corresponding to shorter data retention than the first write mode. The first and second write modes are characterized by first and second sets of resistance ranges in the different sets of resistance ranges. The method includes periodically refreshing data values in memory cells storing data in the second write mode.

Memory with multiple levels of data retention

A digital video multiplex processing method comprises the following steps: setting a normal play index and a fast play index; performing a normal recording/playback action of a video data; determining whether to let the video data enter a cue-and-jump action; taking track of the fast play index in the video data; performing conversion of the video data; and setting the normal play index to be equal to the fast play index. A digital video multiplex processing device comprises a video medium readout unit, a drive interface unit, a data regulation unit, a data buffer unit, an image decoding unit, a sound decoding unit, an image processing unit, a sound processing unit, and a control unit. The control unit is used to receive operation instructions of a user to control the operation of the digital video multiplex processing device.
