摘要:
A memory system is provided, which includes a nonvolatile memory module including a plurality of nonvolatile memory devices, and a memory module controller configured to control the nonvolatile memory module. At least two nonvolatile memory devices of the plurality of nonvolatile memory devices are configured to store serial presence detect (SPD) information. The memory module controller is configured to read the SPD information from the nonvolatile memory module and to set a communication mode with the nonvolatile memory module based on the read SPD information.

A semiconductor memory device includes a memory cell array of nonvolatile memory cells having a variable resistance element, and a conductor line array capable of generating a compensation magnetic field for the nonvolatile memory cells. A current driver selectively supplies current to conductive lines, a magnetic field sensor senses an applied external magnetic field and generates external magnetic field information, and a controller controls generation of the compensation magnetic field in response to the external magnetic field information.

A method is provided for controlling a write operation in a nonvolatile memory device to provide wear leveling, where the nonvolatile memory device includes multiple memory blocks. The method includes reading write indication information with respect to at least a selected memory block of the multiple memory blocks; determining whether a write order of data to be stored in the selected memory block is an ascending order or a descending order, based on the write indication information of the selected memory block; and generating addresses of memory regions in the selected memory block in an ascending order when the write order of the data is determined to be an ascending order, and generating addresses of the memory regions in the selected memory block in a descending order when the write order is determined to be a descending order.
