soft error, device

An erroneous output signal from a latch or memory cell that can be corrected by performing one or more normal functions of the device containing the latch or memory cell.

NOTE 1 As commonly used, the term refers to an error caused by radiation or electromagnetic pulses and not to an error associated with a physical defect introduced during the manufacturing process.

NOTE 2 Soft errors can be generated from SEU, SEFI, MBU, MCU, and/or SET. The term SER, which includes a variety of soft error mechanisms, has been adopted by the commercial industry while the more specific terms SEU, SEFI, etc. are typically used by the avionics, space, and military electronics communities.
