Data write method, memory controller and memory device



The invention relates to a data write method, a memory controller and a memory device. The method is used for a rewritable nonvolatile memory module with multiple physical blocks. Each physical block has a plurality of physical pages; part of the physical blocks map a plurality of logical blocks; and each logical block has a plurality of logical pages. The method comprises the following steps: receiving data, wherein the data has a plurality of data bits and belongs to one logical page; judging whether every data bit is a specific value; and when every data bit is a specific value, not writing the data into the physical page. Thus, the method provided by the invention can enhance the efficiency of the memory device.
