Abstract
Techniques are provided for a register file cell that includes a primary storage portion configured to store a first value, and a secondary storage portion that is coupled to the primary storage portion. The secondary storage portion is configured to function as a scan latch during a test operation, and is further configured to store a second value during normal operation. The second value is a duplicate of the first value. The cell further includes an error detection portion that is coupled to the primary storage portion and the secondary storage portion and is configured to indicate a difference between the first value and the second value, caused by a soft error.
