Provided are a semiconductor device and a method of operating the same. A semiconductor includes a test circuit which comprises: a test transistor to be tested for time-dependent dielectric breakdown (TDDB) characteristics using a stress voltage; an input switch disposed between a voltage application node to which the stress voltage is applied and an input node which transmits the stress voltage to the test transistor; and a protection switch disposed between the input node and a ground node.

A novel mobile station for a CDMA system does not repeat initial pilot acquisition, when a call is abnormally released. The mobile station performs energy measurement on PN offset values of the neighbor base stations, received from the previous service base station, to determine a reference active sector. Based on whether the determined sector is identical to the previous reference active sector, call re-origination is performed from the sync channel state or the paging channel state. Accordingly, the user shouldn't have to redial and wait for a long time until the call re-origination is performed successfully. In addition, the mobile station does not need to perform initial pilot acquisition unnecessarily, and can reduce the time required for recovering the dropped call.
