摘要:
A nonvolatile memory module may include a nonvolatile memory device, a nonvolatile memory controller configured to control the nonvolatile memory device, a volatile memory device configured as a cache memory of the nonvolatile memory device, and a module controller configured to receive a command and an address from an external device, external to the nonvolatile memory module, and to send a volatile memory command and a volatile memory address to the volatile memory device through a first bus and a nonvolatile memory command and a nonvolatile memory address to the controller through a second bus in response to the received command and address. The volatile memory device is configured to load two or more cache data on each of two or more memory data line groups and two or more tags on each of two or more tag data line groups in response to the volatile memory address.
