    Abstract: An electronic system includes first, second, third, and fourth integrated circuit dies. The third integrated circuit die has a first voltage regulator circuit. A supply voltage output of the first voltage regulator circuit is coupled to provide a first supply voltage to a supply voltage input of the first integrated circuit die. The first voltage regulator circuit generates a first power ready signal that indicates when the first supply voltage has reached a first threshold voltage. The fourth integrated circuit die has a second voltage regulator circuit that generates a second supply voltage in response to the first power ready signal. A supply voltage output of the second voltage regulator circuit is coupled to provide the second supply voltage to a supply voltage input of the second integrated circuit die.

    Abstract: An integrated circuit includes a first voltage decrease detection circuit that has a first comparator circuit that compares a supply voltage in the integrated circuit to a threshold voltage to generate a first detection signal that indicates a decrease in the supply voltage, and a first timestamp storage circuit that stores a first timestamp in response to the first detection signal indicating the decrease. The integrated circuit includes a second voltage decrease detection circuit that has a second comparator circuit that compares the supply voltage to the threshold voltage to generate a second detection signal that indicates the decrease, and a second timestamp storage circuit that stores a second timestamp in response to the second detection signal indicating the decrease. The integrated circuit includes a control circuit that determines a location of a source of the decrease in the integrated circuit based on the first and the second timestamps.

    Abstract: An integrated circuit configured to execute multiple operations in parallel is provided. The integrated circuit may be organized into multiple logic sectors. Two or more groups of logic sectors may be executed in an interleaved fashion, where successive groups of logic sectors are activated after a predetermined amount of delay. The integrated circuit may include an array of memory cells. Rows of the memory cells may be accessed in an interleaving manner, where successive rows of memory cells are selected after a predetermined amount of delay. Operating groups of circuit components using an interleaving scheme can help improve operational efficiency while reducing power supply noise without having to increase die area for on-die decoupling capacitance.
