Abstract
A semiconductor device includes: first to Nth input terminals (where N is an integer equal to or greater than 2); and a redundant input terminal. When a Kth input terminal (where K is an integer ranging from 1 to N−1) is defective among the first to Nth input terminals, (K+1)th to Nth input terminals receive signals of Kth to (N−1)th input terminals, respectively, and the redundant input terminal receives a signal of the Nth input terminal.
Claims16
A semiconductor device, comprising:
- first to Nth input terminals (where N is an integer equal to or greater than 2);
- and
- a redundant input terminal,
- wherein when a Kth input terminal (where K is an integer ranging from 1 to N−1) is defective among the first to Nth input terminals, (K+1)th to Nth input terminals receive signals of Kth to (N−1)th input terminals, respectively, and the redundant input terminal receives a signal of the Nth input terminal.
A semiconductor device, comprising:
- first to Nth input terminals (where N is an integer equal to or greater than 2);
- (N+1)th to 2Nth input terminals;
- and
- a redundant input terminal,
- wherein when a Kth input terminal (where K is an integer ranging from 1 to N−1) is defective among the first to Nth input terminals, (K+1)th to Nth input terminals receive signals of Kth to (N−1)th input terminals, respectively, and the redundant input terminal receives a signal of the Nth input terminal, and
- when a Jth input terminal (where J is an integer ranging from (N+1) to (2N−1)) is defective among the (N+1)th to 2Nth input terminals, (J+1)th to 2Nth input terminals receive signals of Jth to (2N−1)th input terminals, respectively, and the redundant input terminal receives a signal of the 2Nth input terminal.
A method for repairing an input terminal of a semiconductor device comprising first to Nth input terminals (where N is an integer equal to or greater than 2) and a redundant input terminal, the method comprising,
- when a Kth input terminal (where K is an integer ranging from 1 to N−1) is defective among the first to Nth input terminals, selecting (K+1)th to Nth input terminals to receive signals of Kth to (N−1)th input terminals, respectively, and the redundant input terminal receiving a signal of the Nth input terminal.
