A memory system having improved signal integrity includes a printed circuit board for use in a memory device, N memory semiconductor packages mounted on the printed circuit board, a first switch mounted on the printed circuit board, a controller mounted on the printed circuit board, N first signal lines connecting the semiconductor packages to the first switch such that the semiconductor packages and the first switch are in an N-to-1 correspondence, a second signal line connecting the first switch to the controller, and N selection lines connecting the semiconductor packages to the first switch such that the semiconductor packages and the first switch are in an N-to-1 correspondence. The N selection lines connect the semiconductor packages to the controller and transmit an enable signal. N is a natural number. |
