Embodiment Construction

[0093] Generally speaking, a memory storage device (also called a memory storage system) includes a rewritable non-volatile memory module and a controller (also called a control circuit). Typically memory storage devices are used with a host system such that the host system can write data to or read data from the memory storage device.

[0094] Figure 1A A host system and a memory storage device are shown according to an exemplary embodiment.

[0095] Please refer to Figure 1A , the host system 1000 generally includes a computer 1100 and an input / output (input / output, I / O) device 1106 . The computer 1100 includes a microprocessor 1102 , a random access memory (random access memory, RAM) 1104 , a system bus 1108 and a data transmission interface 1110 . The input / output device 1106 includes such as Figure 1B mouse 1202, keyboard 1204, monitor 1206 and printer 1252. It is important to understand that Figure 1B The devices shown are not limited to the input / output device 1...

Abstract

A data processing method, memory controller and memory storage device. The data processing method is used in a rewritable non-volatile memory module. The method includes receiving a write data string belonging to a logical access address of a logical programming unit; selecting a first physical programming unit; and determining whether the write data string belongs to a pattern. This method includes, if the write data string belongs to this mode, setting the identification information corresponding to this logical access address to the identification value corresponding to this mode, and storing the identification information corresponding to this logical access address to a preset Assume an area where this write data string will not be programmed into the selected physical programming unit. The method also includes mapping the logical programming unit to the selected physical programming unit. Based on this, this method can effectively shorten the time required to write data.

Description

technical field [0001] The invention relates to a data processing method for a rewritable non-volatile memory module, a memory controller and a memory storage device using the method. Background technique [0002] Digital cameras, mobile phones, and MP3 players have grown rapidly in recent years, making consumers' demand for storage media also increase rapidly. Since the rewritable non-volatile memory (for example, flash memory) has the characteristics of non-volatility of data, power saving, small size, and no mechanical structure, it is very suitable for being built in various portable devices such as the above examples. in the multimedia device. [0003] Generally speaking, the rewritable non-volatile memory includes a plurality of physical erasing units, and each physical erasing unit includes a plurality of physical programming units, wherein the physical programming unit is the smallest writing unit. Therefore, when the size of the data to be written is smaller than ...
