ABSTRACT:
An integrated circuit device provided with (a) an auto-clear circuit for outputting an auto-clear signal in response to a supply of the power source, (2) a mode signal generating circuit for generating a burn-in mode signal or test mode signal based on the auto-clear signal, and for generating a normal mode signal based on a reset signal or operation start signal, and (3) a mode setting circuit for making one of the burn-in setting and the test mode setting respectively in response to the burn-in mode signal and test mode signal, whichever inputted, and for making normal mode setting upon input of the normal mode signal. The present integrated circuit device omits a mode-setting-only input terminal which used to be provided separately only for making the burn-in setting or test mode setting. As a result, a system employing the present integrated circuit device can be designed more flexibly and downsized as well.
