Abstract
A fuse apparatus for controlling a built-in self stress unit includes a built-in self stress configured to repeatedly generate any stress test pattern in a test mode, and generate a one-cycle end signal when one cycle for the generated stress test pattern has ended, and a fuse configured to record an operation state of the built-in self stress according to the one-cycle end signal. A method for controlling a built-in self stress includes repeatedly generating any stress test mode, in a test mode counting the generated stress test pattern, and activating a cycle end signal when a counting value reaches a predetermined value, and recording an operation state of the built-in self stress in a fuse on the basis of the counted value.
