Abstract: A memory system is disclosed, comprising a primary memory module, a secondary memory module, and a controller. The controller is configured to identify addresses in the primary memory module requiring correction, and is further configured to receive a memory access request identifying an address in the primary memory module. The controller is configured to determine whether the address is identified as requiring correction and, if it is not, to direct the memory access request to the primary memory module. If the address is identified as requiring correction, the controller is configured to direct the memory access request to the secondary memory module.

Abstract: A circuit for delivering power to a load from a wireless power supply comprises an inductor coil for placing in the electromagnetic field of an inductor coil of a supply and a switchable capacitor bank with capacitors switchable at least between a series and a parallel configuration. The voltage across the capacitor bank is used as a feedback control parameter for controlling the capacitor bank switching. A voltage regulator is used to supply the load with a constant voltage power supply derived from the capacitor bank output.

Abstract: An electronic device includes a digital circuit, a power delivery subsystem configured to provide a supply voltage and a body-biasing voltage to the digital circuit, and a controller a controller coupled to the power delivery subsystem. The controller is configured to determine a process parameter for the electronic device, determine a current temperature parameter for the electronic device, concurrently determine a first coarse-grain level for the supply voltage and a second coarse-grain level for the body-biasing voltage based on the process parameter, the current temperature parameter, and a frequency of a clock signal to be supplied to the digital circuit, and to determine a fine-grain level for the supply voltage.
