An error-handling method, an associated data storage device and the controller thereof are provided. The error-handling method may include: uploading an error-handling program to a buffer memory equipped with error correction code (ECC) protection capability; in response to at least one error, interrupting execution of a current procedure and activating an interruption service; executing the error-handling program on the buffer memory; disabling a transmission interface circuit; resetting at least one hardware engine and at least one NV memory element; performing cache rearrangement regarding a data cache within the data storage device, and programming rearranged cache data into the NV memory element, to perform data recovery; and through activating a watchdog module and the transmission interface circuit and relinking with a host device, completing soft reset to make the data storage device operate normally again.

Error-handling method, associated data storage device and controller thereof

A data management method includes steps of: receiving a read command; reading a page containing target data from a non-volatile memory when the target data corresponding to the read command is stored in the non-volatile memory; determining whether a count of reading of the page is greater than a read threshold; and if false, storing at least one record of subsequent data into a first storage space of a data buffering storage device; or if true, storing the at least one record of subsequent data into a second storage space of the data buffering storage device. Both of the target data and the at least one record of subsequent data are stored in the page, and the target data and the at least one record of subsequent data have a sequential relationship in terms of data reading. Another data management method and a corresponding data storage device are also provided.

Data storage device and data management method for data storage device

An operating method of a memory controller includes steps of: configuring the memory controller to receive a read command and read at least one piece of first data stored in a non-volatile memory according to the received read command; configuring the memory controller to determine whether a read count of the at least one piece of first data is greater than a set value; and configuring the memory controller to copy and store the at least one piece of first data in a data temporary storage device when the read count of the at least one piece of first data is determined to be greater than the set value. A data storage device and another operating method are also provided.
