  • Patent number: 9631982
    Abstract: A semiconductor device that may include at least one temperature sensing circuit is disclosed. The temperature sensing circuits may be used to control various operating parameters to improve the operation of the semiconductor device over a wide temperature range. In this way, operating specifications of a semiconductor device at worst case temperatures may be met without compromising performance at other operating temperatures. The temperature sensing circuit may provide a plurality of temperature ranges for setting the operational parameters. Each temperature range can include a temperature range upper limit value and a temperature range lower limit value and adjacent temperature ranges may overlap. The temperature ranges may be set in accordance with a count value that can incrementally change in response to the at least one temperature sensing circuit.

  • Patent number: 9613719
    Abstract: A method of healing a plurality of non-volatile semiconductor memory devices on a multi-chip package is disclosed. The multi-chip package can be heated to a temperature range having a temperature range upper limit value and a temperature range lower limit value. The temperature of the multi-chip package can be kept essentially within the temperature range for a predetermined time period by monitoring a thermal sensing element with a sensing circuit outside of the multi-chip package. The thermal sensing element may be located near the components with the lowest failure temperature to ensure the multi-chip package is not damaged during the healing process.

  • Patent number: 9508692
    Abstract: A package can include a first, second and third semiconductor devices stacked in a first direction. A first semiconductor device can include a first through via between a first side and a second side opposite the first side of the first semiconductor device and a first circuit that provides a first reference potential at a first circuit output, electrically connected to the first through via in a normal mode of operation. A second semiconductor device can include a second through via, a second circuit, and a third circuit. A second circuit can be electrically connected to the first through via at the second side. A third circuit can provide a second reference potential and can be electrically connected to the second through via at the first side. The third circuit and the third semiconductor device can receive the second reference potential exclusive of the first semiconductor device.
