ABSTRACT:
A memory system that includes a plurality of memory devices includes: a controller for outputting a first clock signal, a second signal and a plurality of command/address input signals corresponding to the plurality of memory devices, respectively; and a register and delay circuit unit for outputting command/address output signals after receiving the command/address input signals front the controller and then correcting transmission delay due to transmission lines; wherein the plurality of memory devices receive the command/address output signals from the register and delay circuit unit via the transmission lines, respectively, and sample the command/address output signals using the first clock signal directly inputted from the controller. As a result, the memory system can simplify the layout of semiconductor device design and prevent the collision of clocks.
