  • Detecting key corruption
    Patent number: 9069988
    Abstract: Corruption in a key stored in a memory is detected by reading a key from a key memory and determining if detection bits of the key read from the key memory correspond to an expected value. The expected value is a value of the detection bits of the key when the key is written to the key memory.

  • METHOD AND APPARATUS FOR COMPENSATING A FREQUENCY GENERATOR SUCH AS AN OSCILLATOR FOR FREQUENCY INACCURACIES
    Publication number: 20150180480
    Abstract: An input receives a generated frequency having a first frequency component and a second frequency component. A filter block includes filter coefficients describing a relationship between the second frequency component and an environmental characteristic. The filter block predicts the first frequency component based on the environmental characteristic, and updates the filter coefficients based on an offset between the predicted first frequency component and a received frequency corresponding to the first frequency component.

  • Integrated circuit system providing enhanced communications between integrated circuit dies and related methods
    Patent number: 8990540
    Abstract: A method may include receiving, at a first integrated circuit die, a memory transaction having an address from a second integrated circuit die.
