Abstract
A semiconductor memory module includes a plurality of semiconductor memory chips and bus signal lines that supply an incoming clock signal and incoming command and address signals to the semiconductor memory chips. A clock signal regeneration circuit and a register circuit are arranged on the semiconductor memory module in a common chip packing connected to the bus signal lines. The clock signal regeneration circuit and the register circuit respectively condition the incoming clock signal and temporarily store the incoming command and address signals, respectively multiply the conditioned clock signal and the temporarily stored command and address signals by a factor of 1:X, and respectively supply to the semiconductor memory chips the conditioned clock signal and the temporarily stored command and address signals.
