REPAIR CIRCUIT, SEMICONDUCTOR APPARATUS AND SEMICONDUCTOR SYSTEM USING THE SAME

摘要

A repair circuit may be provided. The repair circuit may include a latch array including a plurality of latch sets. The repair circuit may include a fuse array including a plurality of fuse sets, and configured to be written, in each fuse set, with repair address data and latch address data which defines a position of a latch set where the repair address data is to be stored, among the plurality of latch sets. The repair circuit may include a first decoder configured to cause data written in any one fuse set among the plurality of fuse sets to be outputted, and a second decoder configured to cause the repair address data to be stored in the latch set corresponding to the latch address data among the plurality of latch sets.
