Abstract
A semiconductor memory module includes a memory module board having at least one semiconductor memory device, an advanced memory buffer (AMB) for receiving the data and the command/address signal from a host and providing the data and the command/address signal to the at least one semiconductor memory device, and a second termination resistor unit located on the memory module board and electrically connected to the AMB. The at least one semiconductor memory device includes a data input buffer for receiving data via a first input terminal and receiving a first reference voltage via a second input terminal, a command/address input buffer for receiving a command/address signal via a first input terminal and receiving a second reference voltage via a second input terminal, and a first termination resistor unit connected to the first input terminal of the data input buffer.
