SEMICONDUCTOR DEVICE

摘要

Disclosed herein is a semiconductor device that includes a plurality of memory cells assigned with addresses that are different from each other, a redundant memory cell replacing a defective memory cell among the memory cells, a fuse circuit storing an address of the defective memory cell, an access control circuit accessing the redundant memory cell when the address of the defective memory cell stored in the fuse circuit is supplied, and a roll call circuit outputting the address of the defective memory cell to outside the semiconductor device in a serial manner.
