    Abstract: This application relates to techniques that adjust the sleep states of a computing device based on user proximity detection procedures. The technique includes detecting a first pattern, using a first subset of sensors of one or more sensors coupled to the computing device, to determine if the object is proximate to the computing device. Provided the first pattern is not indicative of the object being proximate to the computing device, the technique detects a second pattern, using a second subset of sensors of the one or more sensors, to determine if the object is proximate to the computing device. Furthermore, provided either the first pattern or the second pattern is indicative of the object being proximate to the computing device and provided a first portion of a computer system within the computing device is operating within a low-power sleep state, the technique causes the first portion to enter into a high-power sleep state.

    Abstract: Techniques are disclosed in which a secure circuit controls a gating circuit to enable or disable other circuitry of a device (e.g., one or more input sensors). For example, the gating circuit may be a power gating circuit and the secure circuit may be configured to disable power to an input sensor in certain situations. As another example, the gating circuit may be a clock gating circuit and the secure circuit may be configured to disable the clock to an input sensor. As yet another example, the gating circuit may be configured to gate a control bus and the secure circuit may be configured to disable control signals to an input sensor. In some embodiments, hardware resources included in or controlled by the secure circuit are not accessible by other elements of the device, other than by sending requests to a predetermined set of memory locations (e.g., a secure mailbox).

    Abstract: In one embodiment, a system includes a non-volatile memory that may serve as both the main memory system and the backing store (or persistent storage). In some embodiments, the non-volatile memory is divided into a main memory portion and a persistent portion. Data in the main memory operation may be encrypted using one or more first keys, and data in the persistent portion may be encrypted using one or more second keys, in an embodiment. The volatile behavior of main memory may be implemented by discarding the one or more first keys in a power down event or other event that indicates a loss of main memory data, while the one or more second keys may be retained. In one embodiment, the physical address space of the non-volatile memory may be a mapping from a second physical address space that is used within the system.

    Abstract: In one embodiment, a system includes a memory that includes a live section and a spares section. The live section may be mapped to the address space of the system, and may be accessed in response to memory operations. Once an entry in the live section has been detected as failed, an entry is in the spares section may be allocated to replace the failed entry. During subsequent accesses to the failed entry, the allocated entry may be used instead. In an embodiment, the failed entry may be coded with an indication of the allocated entry, to redirect to the allocated entry. In one implementation, for example, the failed entry may be coded with N copies of a pointer to the allocated entry, each copy protected by corresponding ECC.
