Embodiment Construction

[0114] Generally speaking, a memory storage device (also called a memory storage system) includes a rewritable non-volatile memory module (rewritable non-volatile memory module) and a controller (also called a control circuit). Typically memory storage devices are used with a host system so that the host system can write data to or read data from the memory storage device.

[0115] figure 1 is a schematic diagram of a host system, memory storage devices, and input / output (I / O) devices shown according to an exemplary embodiment of the present invention. figure 2 It is a schematic diagram showing a host system, a memory storage device and an I / O device according to another exemplary embodiment of the present invention.

[0116] Please refer to figure 1 and figure 2 , the host system 11 generally includes a processor 111 , a random access memory (random access memory, RAM) 112 , a read only memory (read only memory, ROM) 113 and a data transmission interface 114 . The proce...

Abstract

The invention provides a data programming method and a memory storage device. The method comprises the following steps of: programming a plurality of first type of entity units in a duplicable nonvolatile memory module so as to store first data; encoding the first data to generated encoded data; receiving second data; and programming at least one of a plurality of second type of entity units corresponding to the first type of entity units in the duplicable nonvolatile memory module so as to store at least part of the second data. According to the method and the device provided by the invention, the ability of correcting errors in paired entity units in multichannel programming programs can be enhanced.

Description

technical field [0001] The invention relates to a memory management mechanism, in particular to a data programming method and a memory storage device. 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 module (such as flash memory) has the characteristics of data non-volatility, 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] As the performance of memory chips continues to increase, some memory devices support multi-channel access. However, although data access efficiency can be improved by increasing the number of channels that can be accessed in parallel, if the amount of data written in parallel at one time is too large or the number of channels used is too large, it may ...
