DATA PROTECTING METHOD, MEMORY STORAGE DEVICE, AND MEMORY CONTROLLER

摘要

A data protecting method, a memory storage device, and a memory controller are provided for a rewritable non-volatile memory module. The data protecting method includes: generating a first error correcting code by using data stored in first memory cells of a plurality of memory cells. The first memory cells are located on first word lines and first bit lines. Among the memory cells located on each of the first bit lines, only one of the memory cells stores the data used to generate the first error correcting code. Accordingly, the data in the memory cells is efficiently protected.
