Abstract: A semiconductor memory device storing memory characteristic information, a memory module including the semiconductor memory device, a memory system, and an operating method of the semiconductor memory device. The semiconductor memory device may include a cell array including a plurality of areas; a command decoder configured to decode a command and generate an internal command; and an information storage unit configured to store characteristic information of at least one of the plurality of areas. When a first command and a first row address accompanying the first command are received, characteristic information of an area corresponding to the first row address is provided to an outside.
