Data write method, memory controller and memory device

数据写入方法、存储器控制器与存储器储存装置

Abstract

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.
本发明涉及一种数据写入方法、存储器控制器与存储器储存装置,其中,方法用于具有多个物理区块的可复写式非挥发性存储器模组,每一物理区块具有多个物理页面,部分的物理区块映射多个逻辑区块并且每一逻辑区块具有多个逻辑页面。本方法包括接收数据,此数据具有多个数据比特并属于一个逻辑页面。本方法也包括判断每一数据比特是否为特定值。并且,本方法包括,当每一数据比特为特定值时,不将此数据写入至物理页面中。基于此,本发明的方法可提升存储器储存装置的效能。
