  • Publication number: 20140211577
    Abstract: A method of operating a semiconductor memory device is disclosed. The method may include receiving an access command, applying a first voltage to a selected word line of the semiconductor memory device for a period of time in response to receiving the access command, applying a second voltage to word lines adjacent to the selected word line before and after the period of time, and applying a third voltage to the word lines adjacent to the selected word line for the period of time, a voltage level of the third voltage greater than the second voltage. The applying the third voltage may occur when the semiconductor memory device is operated at a temperature below the predetermined temperature.

  • Patent number: 8396682
    Abstract: A semiconductor device is provided. The semiconductor device applies data applied through a bump pad on which a bump is mounted through a test pad to a test apparatus such that the reliability of the test can be improved. The amount of test pads is significantly reduced by allowing data output through bump pads to be selectively applied to a test pad. Data and signals applied from test pads are synchronized with each other and applied to bump pads during a test operation such that the reliability of the test can be improved without the need of an additional test chip.
