What are soft errors and what causes them?
As IC device technology scales to smaller and smaller feature sizes, the subject of soft errors is gaining importance in the design of reliable systems. A soft error is the upset in memory, static logic or combinational logic. The term "soft" is used because the upset is not due to any permanent damage of the circuit. If the error can be detected and corrected, the device can be returned to its proper operating condition without any service intervention.
