Abstract
A memory storage device is provided. The memory storage device includes a connector, a rewriteable non-volatile memory module, a second temporary memory and a memory controller having a first temporary memory. The memory controller receives a write command and the write data, and temporarily stores the write data into the first temporary memory. The memory controller also copies the write data into the second temporary memory from the first temporary memory and, based on the write command, writes the write data into the rewriteable non-volatile memory module. Additionally, the memory controller determines whether a program fail occurs when executing the write command. If the program fail occurs, the memory controller reads the write data from the second temporary memory and re-execute the write command. Therefore, a write speed of the memory storage device can be effectively improved.
