ABSTRACT:
A DLL Reset signal for delivering Fuse data from anti-fuses is generated from a reset signal which is supplied asynchronous to a clock when an initial setting is made. The DLL Reset signal is supplied to an anti-fuse block which comprises a plurality of anti-fuses, such that the delay amount of an internal signal is switched to a desired value in accordance with the Fuse data written into the anti-fuses.
