Abstract: A semiconductor device and method of operation having reduced read time of fuse array information during boot-up operation. When fuse array information is read, only repaired fuse-set information is read such that a read time of the semiconductor memory device is reduced, resulting in an increased read margin.

Abstract: A semiconductor device may include a fuse array configured to output fuse data. The semiconductor device may include a latch circuit configured to store the fuse data during an enabled section of a dummy boot-up signal, output the stored fuse data as a fuse data information signal during a disabled section of the dummy boot-up signal, and fix the fuse data information signal to a specific level during the enabled section of the dummy boot-up signal regardless of the stored fuse data.

Abstract: The monitoring circuit of a semiconductor device includes: a boot-up controller configured to generate a boot-up enable signal in response to a power-up signal and a boot-up command signal; a read-period generator configured to output a read-period signal in response to a boot-up read signal; and a monitoring unit configured to output the read-period signal to an external output terminal during activation of the boot-up enable signal to allow the read-period signal to be monitored.
