Abstract
A data writing method, a memory storage device, and a memory controller for controlling a rewritable non-volatile memory module are provided. The rewritable non-volatile memory module includes at least one memory chip, and each memory chip includes a plurality of physical erasing units. The data writing method includes following steps. A data is written into at least one first physical erasing unit. A first error correction code and a second error correction code are respectively generated according to the data, where a number of bits correctable to the second error correction code is greater than a number of bits correctable to the first error correction code. The second error correction code is written into a second physical erasing unit. The first physical erasing unit and the second physical erasing unit belong to the same memory chip. Thereby, the memory space can be efficiently used.
