Abstract

The present invention provides a semiconductor integrated circuit that is provided with an address generation circuit that selectively generates an address of a memory cell substituted by a redundancy memory cell based on a defective memory cell address retained in an address retention circuit, and a control circuit that selectively tests the redundancy memory cell by performing a retest on whether the substitution is successful or not based on the address generated by the address generation circuit.
