Embodiment Construction

[0061] 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 so that the host system can write data to or read data from the memory storage device.

[0062] Figure 1A A host system and a memory storage device are shown according to an exemplary embodiment.

[0063] 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 temporary memory (such as random access memory, RA) 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 1208. It is important to understand that Figure 1B The devices shown are not limited to the input / output device ...

Abstract

The invention discloses a memory storage device and a memory controller and a data writing method thereof. The memory storage device comprises a connector, a reproducible nonvolatile memory module, a second scratch pad memory and the memory controller with a first scratch pad memory. The memory controller is used for receiving a writing command and write data and temporarily storing the write data into the first scratch pad memory. The memory storage further replicates the write data into the second scratch pad memory and writes the write data into the reproducible nonvolatile memory module according to the writing command. Moreover, the memory controller is further used for judging whether a program error is generated when the writing command is executed and reading the write data from the second scratch pad memory and executing the writing command again when the program error is generated. Therefore, the writing speed of the memory storage device can be effectively promoted.

Description

technical field [0001] The invention relates to a memory storage device, in particular to a memory storage device, a memory controller and a data writing method capable of effectively increasing the writing speed. 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. Because rewritable non-volatile memory (rewritable non-volatile memory) has the characteristics of data non-volatility, power saving, small size, no mechanical structure, and fast read and write speed, it is most suitable for portable electronic products, such as notebooks. computer. A solid state drive is a memory storage device that uses flash memory as a storage medium. Therefore, the flash memory industry has become a very popular part of the electronics industry in recent years. [0003] If the memory storage device uses a rewritable volatile memory as the storage medium, when dat...
