A circuit for selecting a block spare in a semiconductor device is designed with a programmable circuit (14), storing an internal address and producing an address match signal AM and a block select signal BS in response to first (A) and second (B) address signals and the internal address. A global spare circuit (28) produces a global spare select signal (GSS), in response to the address match signal. A block spare circuit (34) produces a block spare select signal (BSS), in response to the global spare select signal and the block select signal.
