Abstract: A data writing method, a memory controller using the method, and a memory storage apparatus using the method are provided. The method includes selecting a physical block as a reserved physical block for a plurality of updated physical blocks. The method also includes, when a host system is about to write updated data into a logical page belonging to a logical block and a physical page, which corresponds to the logical page, of a substitute physical block, which corresponds to an updated physical block mapped to the logical block, has stored data, independently assigning the reserved physical block to the updated physical block mapped to the logical block and writing the updated data into the reserved physical block. Accordingly, the method can complete data writing without performing a data merge operation, thereby shortening the time for performing a write command.

Abstract: A data access method for accessing a non-volatile memory module is provided. The data access method includes configuring a plurality of logical addresses and grouping the logical addresses into logical blocks to map to the physical blocks of the non-volatile memory module, and a host system formats the logical addresses into one partition by using a file system and the partition stores at least one file and a file description block corresponding to the file. The data access method further includes searching an end mark corresponding to entry values of the file description block, setting logical addresses storing the end mark as default pattern addresses, and setting values stored in the logical addresses as default values corresponding to the default pattern addresses. Accordingly, the data access method can divide one partition into a write protect area and a writable area by updating data stored in the default pattern addresses.

Abstract: A data writing method for writing data into physical blocks of a memory storage apparatus, and a memory controller and a memory storage apparatus using the same are provided, the physical blocks are grouped into a plurality of physical units. The method includes switching the speed mode of the memory storage apparatus into a first speed mode or a second speed mode according to a command and a work frequency received from a host system. The method also includes selecting a first writing mode to write the data into the physical units when the speed mode is the first speed mode. The method further includes selecting a second writing mode to write the data into the physical units when the speed mode is the second speed mode. Accordingly, the method can effectively shorten the time of executing a write command from the host system.

Abstract: A data writing method for a rewritable non-volatile memory module is provided. The method includes receiving at least one update data, wherein the update data belongs to at least one logical page of a first logical block, and the first logical block is mapped to a first physical block. The method also includes when a physical page of a second physical block that is corresponding to the logical page already stores data, selecting a third physical block from a free area, writing the update data into the third physical block, serving the third physical block as the child physical block of the first physical block, and executing an erasing operation on the second physical block, wherein the second physical block is currently a child physical block of the first physical block. Thereby, the method can effectively reduce the number of operations for merging data and increase the data writing speed.

Abstract: A flash memory storage system having a flash memory controller and a flash memory chip is provided. The flash memory controller configures a second physical unit of the flash memory chip as a midway cache physical unit corresponding to a first physical unit and temporarily stores first data corresponding to a first host write command and second data corresponding to a second host write command in the midway cache physical unit, wherein the first and second data corresponding to slow physical addresses of the first physical unit. Then, the flash memory controller synchronously copies the first and second data from the midway cache physical unit into the first physical unit, thereby shortening time for writing data into the flash memory chip.

Abstract: A data writing method for writing data into a flash memory chip is provided, wherein the flash memory chip includes a plurality of physical units. The data writing method includes providing a flash memory control circuit and configuring a plurality of logical units, wherein each logical unit is mapped to at least one physical unit. The data writing method also includes configuring a plurality of logical addresses and mapping the logical addresses to the logical units, wherein at least one logical unit is mapped to at least two non-continuous logical addresses. The data writing method further includes writing the data from a host system into the corresponding physical units according to the logical units mapped to the logical addresses through the flash memory control circuit. Thereby, the data to be moved while writing data into the physical units is reduced, and accordingly the data writing speed is effectively increased.
