Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a DRAM compression scheme to reduce power consumption in motion compensation and display refresh.SOLUTION: Systems and methods of operating a memory controller provided for receiving a write request from a motion compensation module are provided, where the write request includes video data. A compression of the video data is conducted to obtain compressed data, where the compression of the video data is transparent to the motion compensation module. In addition, the compressed data can be stored in one or more memory chips. Moreover, a read request is received, where stored data is retrieved from at least one of the one or more memory chips in response to the request. Additionally, a decompression of the stored data may be conducted to obtain decompressed data.
