Semiconductor memory device having program circuit

摘要

A memory core part includes a program part and a voltage supply part. The program part includes a program structure part, a latch part and an address compare part. The program structure part includes an electric fuse blown with a program voltage. The voltage supply part supplies the program voltage to the program part every repair address. The latch part holds the program state in the program structure part on the basis of a transfer signal. The address compare part outputs a spare determination result on the basis of an input address and the latched program state.
