Abstract
A semiconductor device may include a media controller configured to output a write requested address when a write request to a nonvolatile memory device is provided from a host; and a cold address manager. The cold address manager may include a stack storing meta data for the write requested address, region information storage configured to manage addresses of the nonvolatile memory device with regions such that length of a region of the regions may vary after a predetermined period, a cold address detector configured to update the stack and the region information storage after the predetermined period and to detect whether an address of the nonvolatile memory device is a cold address, the cold address having write requests performed at less than a predetermined level.
