Abstract
A data writing method for writing data into physical blocks of a memory storage apparatus, and a memory controller and a memory storage apparatus using the same are provided, the physical blocks are grouped into a plurality of physical units. The method includes switching the speed mode of the memory storage apparatus into a first speed mode or a second speed mode according to a command and a work frequency received from a host system. The method also includes selecting a first writing mode to write the data into the physical units when the speed mode is the first speed mode. The method further includes selecting a second writing mode to write the data into the physical units when the speed mode is the second speed mode. Accordingly, the method can effectively shorten the time of executing a write command from the host system.
