Abstract: 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.

Abstract: 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.

Abstract: Embodiments relate to reliably storing information in a sensor or other device. In an embodiment, information storage circuitry comprises independent, redundant memory portions and error detection circuitry. The circuit can operate in cooperation with a memory writing procedure that utilizes a validity bit and sequentially writes to one or the other of the redundant memory portions such that at least one of the memory portions has data that is valid and can be recognized as such.
