Abstract:
A magnetic random access memory (MRAM), and a memory module, memory system including the same, and method for controlling the same are disclosed. The MRAM includes magnetic memory cells configured to change between at least two states according to a magnetization direction, and a mode register supporting a plurality of operational modes.

Claim (Index 1):
A memory system comprising:\n a memory controller; and a magnetic random access memory (MRAM) communicatively coupled to the memory controller, the MRAM including a mode register and magnetic memory cells, the mode register configured to support a plurality of operational modes of the MRAM, each of the magnetic memory cells including a magnetic tunnel junction (MTJ) including a free layer, a pinned layer, and a tunnel layer between the free layer and the pinned layer, each of the magnetic memory cells configured to change between at least two states according to a magnetization direction of the MTJ, and a magnetization direction of the free layer being either parallel or antiparallel to a magnetization direction of the pinned layer, wherein the memory controller is configured to select a mode register set code and to output a plurality of command signals, a clock signal, a data strobe (DQS) signal and data input/output (DQ data) to the MRAM, a part of the plurality of command signals including the mode register set code, wherein the MRAM is configured to set the mode register according to the mode register set code, and wherein the mode register is configured to be used for one or more of the following:\n to provide a write leveling function to compensate for a skew between the clock signal and the DQS signal received from the memory controller; and \n to provide a write Cyclic Redundancy Check (CRC) function to enable CRC calculation of data transmitted between the MRAM and the memory controller.
