Abstract
A fuse apparatus for controlling a built-in self stress unit including 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 a operation state of the built-in self stress according to the one-cycle end signal.
Claims14
A fuse apparatus for controlling a built-in self stress, comprising:
- a built-in self stress unit configured repeatedly to 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 fuse apparatus for controlling a built-in self stress, comprising:
- a built-in self stress unit 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;
- a counting unit configured to count the one-cycle end signal generated in the built-in self stress unit;
- a comparator configured to compare the output of the counter with a predetermined value;
- and
- a fuse configured to record the output of the comparator to record a operation state of the built-in self stress unit.
