Abstract: A non-volatile memory has a first payload data region and a first redundant memory area associated with the first payload data region. The first redundant memory area has a first portion, a second portion and a third portion. The first portion includes first payload error correction code (ECC) data associated with the first payload data region. The second portion includes first metadata associated with the first payload data region. The third portion includes first metadata ECC data associated with the first metadata.

Abstract: An audio system is disclosed and includes a semiconductor device having an analog-to-digital converter (ADC) system and includes a controller and a programmable control register coupled to the controller. The ADC system also includes a plurality of channels coupled to the controller, each channel having an associated schedule bit within the programmable control register, an associated request bit within the programmable control register, and an associated interrupt request bit within the programmable control register. The ADC system also includes a scheduler coupled to the controller and to the programmable control register, the scheduler comprising logic to monitor a plurality of request bits to detect when any of the schedule request bits are set. Further, the semiconductor device includes a digital-to-analog converter (DAC) system coupled to the analog-to-digital converter system.

Abstract: A method of scheduling use of an analog-to-digital converter is disclosed and includes writing to a schedule register that has a plurality of schedule bits. Each of the plurality of schedule bits corresponds to a channel of an analog-to-digital converter. Further, the method includes copying the plurality of bits from the schedule register to a request register that has a plurality of request bits. The method also includes monitoring the plurality of request bits and determining whether at least one of the plurality of request bits is set. Additionally, the method includes blocking further copying to the request register after determining that at least one of the plurality of request bits is set.
