  • Patent number: 11940822
    Abstract: A semiconductor device includes an analog voltage regulator and an integrated circuit module. The analog voltage regulator generates a regulated output voltage. The integrated circuit module generates an analog sense voltage based on the regulated output voltage and includes integrated circuit dies, a first sensor, second sensors, and a digital voltage offset controller (DVOC). The first sensor generates a digital reference voltage based on an analog reference voltage. The second voltage sensors detect voltages at predetermined locations on the integrated circuit dies. The DVOC generates a digital offset voltage substantially equal to the difference between the digital reference voltage and the voltage detected by a selected one of the second voltage sensors. The regulated output voltage is based on an unregulated input voltage, the analog sense voltage, and the digital offset voltage.

  • Publication number: 20230343754
    Abstract: A plurality of semiconductor devices are arranged in a stack. Individual semiconductor devices within the stack are selected by an identity signal sent into the stack. The signal is compared within each stack to a unique stack identifier stored within each of the semiconductor devices and, when the signal is the same as the unique stack identifier, the semiconductor device is selected while, when the signal is not the same as the unique stack identifier, the semiconductor device remains within the default bypass mode.
