Semiconductor device having redundant select line to replace regular select line
Abstract:
Disclosed herein is a semiconductor device that includes selection lines selected based on an access address, a first hit signal generation circuit activating a first hit signal when the access address is coincident with a programmed address that designates a defective selection line included in the selection lines, and a first redundant selection line selected when the first hit signal is activated. The first hit signal generation circuit deactivates the first hit signal when a value of the access address is in a first address range even if the access address is coincident with the programmed address.
