ABSTRACT:
A semiconductor memory module includes a memory module board having at least one semiconductor memory device. The semiconductor memory device includes a data input buffer that receives data and a first reference voltage via first and second input terminals, a command/address buffer that receives a command/address signal and a second reference voltage via first and second input terminals, and a first termination resistor unit connected to the first input terminal of the data input buffer. The semiconductor memory module further includes a second termination resistor unit located on the memory module board and connected to an internal command/address bus. The first termination resistor unit includes a first resistor connected between a first voltage source and the first input terminal of the data input buffer, and the second termination resistor unit includes a second resistor connected between a second voltage source and the first input terminal of the command/address input buffer.
