An information storage circuit having a first memory portion configured to store a first validity bit and first data; a second memory portion configured to store a second validity bit and second data; and a subcircuit configured to: write the first data to the first memory portion and the second data to the second memory portion sequentially; and set the first and second validity bits to indicate which of the first data and second data is valid.

Systems and methods for storing information

An apparatus and corresponding method for outputting a protocol pulse based on a speed signal representing speed of an object. The apparatus includes a zero-crossing circuit, and a delay circuit. The zero-crossing circuit is configured to output the protocol pulse at a zero-crossing of the speed signal. The delay circuit is coupled to the output of the zero-crossing circuit and configured to delay the protocol pulse. A first edge of the protocol pulse is asynchronous with a clock, and a second edge of the protocol pulse is synchronous with the clock.

Asynchronous output protocol

Embodiments relate to multi-contact sensor devices and operating methods thereof that can reduce or eliminate offset error. In embodiments, sensor devices can comprise three or more contacts, and multiple such sensor devices can be combined. The sensor devices can comprise Hall sensor devices, such as vertical Hall devices, or other sensor types in embodiments. Operating modes can be implemented for the multi-contact sensor devices which offer significant modifications of and improvements over conventional spinning current principles, including reduced residual offset.
