ABSTRACT:
A semiconductor memory apparatus of the present invention comprises a semiconductor memory circuit and a test mode control circuit, the test mode control circuit sets a source voltage to a second voltage, which is larger than a first voltage used at the time of the normal operation, and controls the semiconductor memory circuit to be set to a predetermined voltage stress test mode by inputting a combination clock signal of clock signals unused at the time of the normal operation.
