Abstract: A method for re-reading page data is provided. The method for re-reading page data classifies each of the retry tables into one of a plurality of retry types, and when starting the re-reading procedure, the method will firstly select a retry type based on the environmental parameters related to reading the target page, and select a retry table from the selected retry type and re-read the data of the target page according to the read parameters of the retry table, thereby reducing a number of times of repetitively reading the target page and preventing read disturbance caused by frequent reading.

Abstract: An optimized operating method for a non-volatile memory. A microcontroller allocates the non-volatile memory to store write data issued by a host. The microcontroller dynamically adjusts a first-writing-mode threshold. The first-writing-mode threshold value is provided for the microcontroller to determine whether to use a first writing mode to allocate the non-volatile memory to store the write data issued by the host. In comparison with the first writing mode, more bits of data are stored in one storage cell in a second writing mode.

Abstract: Optimized writing techniques for nonvolatile memory are presented. A microcontroller switches between a first writing mode and a second writing mode to write data to the nonvolatile memory. The switching between the first writing mode and the second writing mode depends on a first accumulated amount of data written to the nonvolatile memory in the first writing mode, or a number of spare blocks of the nonvolatile memory that is evaluated after a garbage collection procedure.

Abstract: An optimized operating method for a nonvolatile memory. A microcontroller allocates the nonvolatile memory to store write data requested by a host. According to a first accumulated amount of data written to the nonvolatile memory in a first writing mode and a second accumulated amount of data written to the nonvolatile memory in a second writing mode, the microcontroller allocates the nonvolatile memory to store write data requested by the host in the first writing mode and in the second writing mode alternately. In comparison with the first writing mode, more bits of data are stored in one storage cell in the second writing mode.
