Abstract

Provided is a memory system in which a pair of differential signals transmitted via a pair of transmission lines are prevented from being terminated at the same voltage during a standby mode, thereby preventing a receiver from entering an unstable state. The memory system includes a pair of transmission lines, a transmitter that outputs a pair of differential signals to the pair of transmission lines, and a receiver that receives the pair of differential signals via the pair of transmission lines. A first termination voltage is applied to one of the pair of transmission lines, and a second termination voltage is applied to the other transmission line. The first termination voltage is determined to be different from the second termination voltage.
