A memory system comprises a memory controller and a memory device having one or more memory ranks and multiple memory electrically connected to the one or more memory ranks. The memory controller includes at least one analysis module and at least one switching determination module. The analysis module analyzes states of multiple memory control commands corresponding to a particular memory rank to generate a control parameter. The switching determination module determines whether at least one switching command is sent according to the control parameter, a current operation mode of the particular memory rank, and an operation state of the particular memory rank. When the memory device receives a first switching command of the at least one command, the particular rank and at least one part of the memory internal circuits are switched from the normal voltage operation mode to the low voltage operation mode.
