Abstract
A system for detecting an address decoding error of a semiconductor device, includes: decoding an original address, with an address decoder of the semiconductor device, to form a corresponding decoded address; recoding the decoded address, with an encoder of the semiconductor device, to form a recoded address; making a comparison, with a comparator of the semiconductor device, of the recoded address and the original address; and detecting an address decoding error based on the comparison.
