Abstract
A semiconductor device may include a media controller configured to output an address in response to receiving a write request for writing to a nonvolatile memory. The semiconductor device may also include a hot address detector. The hot address detector is configured to store a list including the address output from the media controller and including meta data related to the address, to update the meta data according to the address output from the media controller, to determine whether the address output from the media controller is a hot address, and to adjust a length of the list.
