Abstract
A reset circuit outputting a reset signal /RESET when detecting an abnormal state in a ring counter is provided. The reset circuit divides the outputs of flip-flops constituting the ring counter into two groups, and check if either of the groups has “H” data. When “H” data exists in both of the two groups or when “H” data does not exist in either of the two groups, the reset circuit activates the reset signal /RESET to L level. Therefore, a semiconductor device can detect an erroneous state and recover to a normal state quickly.
