A post package repair (PPR) device is disclosed, which relates to a technology for masking a rupture operation in case of a post package repair (PPR) operation. The post package repair (PPR) device includes: a plurality of bank groups, each including a fuse indicating repair information, configured to share a predetermined number of fuses; a resource detection unit configured to generate a resource signal which determines whether the fuses from among the plurality of bank groups are available; and a masking controller configured to output a masking signal which prevents repeated execution of a rupture operation when there is no unused fuse in response to the resource signal and a bank active signal.
