Embodiment Construction

[0083] Figure 1A It is a schematic block diagram of a host system and a memory storage device according to an exemplary embodiment.

[0084] Please refer to Figure 1A The host system 1000 includes a microprocessor 1102, a storage device 1104, a random access memory 1106, and an input / output device 1108. When the host system 1000 is turned on, the microprocessor 1102 executes the operating system 1110 installed in the storage device 1104, so that the host system 1000 provides corresponding functions according to the user's operation. For example, in this exemplary implementation, the host system 1000 is a computer system and the operating system 1110 is a Windows operating system, and when the host system 1000 is turned on, the user can operate the host system 1000 through the input / output device 1108 to perform file editing, Video file editing, video playback and other functions.

[0085] The memory storage device 100 is electrically connected to the host system 1000, and performs...

Abstract

The invention discloses a memorizer formatting method, a memorizer controller and a memorizer memory device. The memorizer formatting method is used for the memorizer memory device. The memorizer formatting method comprises the following steps of collocating logical block addresses for mapping part of physical blocks; generating first and second file system data according to the size of the logical block addresses; memorizing the first file system data in a first physical block, wherein the first physical block is used for mapping a first logical block address in the logical block addresses; selecting a second physical block from the physical blocks; memorizing the second file system data in the second physical block; judging whether a formatting command is received or not; and mapping the first logical block address to the second physical block again when the formatting command is received.

Description

Technical field [0001] The invention relates to a method for performing memory formatting and a memory controller and a memory storage device using the method. Background technique [0002] Digital cameras, mobile phones and MP3 players have grown rapidly over the past few years, which has led to a rapid increase in consumer demand for storage media. Since the rewritable non-volatile memory (for example, flash memory) has the characteristics of non-volatile data, power saving, small size, and no mechanical structure, it is very suitable for the built-in various portable types mentioned above. In the electronic device. [0003] Generally speaking, a rewritable non-volatile memory device must undergo a formatting process before it can be used to store data. Or, when the user wants to completely delete all data stored in the rewritable non-volatile memory device, the user will format the rewritable non-volatile memory storage device. However, as the capacity of the rewritable non-v...
