Abstract:
A system includes a controller which is capable of operating at one of a first speed and a second speed slower than the first speed; a semiconductor memory apparatus operating at the first speed; and an input/output device which is connected between the semiconductor memory apparatus and the controller, and configured to control input/output of signals between the controller and the semiconductor memory apparatus, wherein the input/output device operates in a normal mode which corresponds to the input/output of the signals between the controller operating at the first speed and the semiconductor memory apparatus and a test mode which corresponds to the input/output of the signals between the controller operating at the second speed and the semiconductor memory apparatus.
