Abstract:
A memory may include a first repair analysis circuit suitable for storing an input fail address when the input fail address is different from a fail address which is already stored in the first repair analysis circuit, and outputting the input fail address as a first transfer fail address when a storage capacity of the first repair analysis circuit is full; and a second repair analysis circuit suitable for storing the first transfer fail address when the first transfer fail address is different from a fail address which is already stored in the second repair analysis circuit.
