ABSTRACT:
A memory system selectively sets signaling modes based on stack position information. The memory system includes a memory module having at least one semiconductor memory device and a memory controller configured to set a signaling mode based on stack position information of each of the semiconductor memory devices. A signaling between the memory controller and each of the semiconductor memory devices is performed in a differential signaling mode, and a signaling among the semiconductor memory devices is performed in a single-ended signaling mode. Accordingly, the memory system has reduced power consumption.
