    Abstract: Apparatus, method, and system for remotely affecting the functionality and lifetime of an integrated circuit are described herein. One embodiment of a method includes: tracking a plurality of operational metrics relating to a monitored device, sending one or more of the plurality of operational metrics to a remote monitor and responsively receiving a command generated by the remote monitor, generating a threat level based on the plurality of operational metrics and the command, and performing a derating action based on the threat level. The command from the remote monitor may be generated by the remote monitor based, at least in part, on the one or more of the plurality of operational metrics. Alternatively, the command may be generated based on information obtained independently by the remote monitor and not based on the one or more of the plurality of operational metrics.

    Abstract: Analog Front End (AFE) driver or transmitter is used for ESD protection of an input-output (IO) pin, thus reducing ESD diode count and subsequently lowering the pad capacitance to achieve high performance in IO circuits like double data rate (DDR) IO, PCI Express (Peripheral Component Interconnect Express), etc. The channel of active devices that constitute AFE driver are used to connect an IO pad to discharge the ESD current to ground, thus providing an alternative path to ESD current and subsequently reducing the ESD diode count. An additional p-type device (Driver Path Enabler (DPE)) is coupled between the IO pad and a gate terminal of the AFE driver. This additional p-type device triggers the channel of the AFE driver. This p-type device is controlled by an RC based structure which cuts the p-type device off during regular operations when power is ramped-up.

    Abstract: A self-adaptive security framework for a device is disclosed. A first security level for a device is set wherein the first security level comprises procedures that authenticate a user and allow the user to access the device. Input from sensors associated with the device may be received at a contextual sensing engine, wherein the input at least includes location data, and wherein at least a portion of the input is related to a physical setting where the device is located. A threat level for the device is determined in the physical setting via the contextual sensing engine based on analyzing the input. The first security level is altered to a second security level to provide an altered threat response for the device based on the threat level wherein the second security level has different procedures to authenticate the user compared to the first security level.
