Semiconductor device and semiconductor memory device

摘要

A semiconductor device includes a fuse array having a plurality of fuse sets suitable for outputting a plurality of fuse status signals having different levels according to whether fuses of the plurality of fuse sets are cut or not, a code counter suitable for counting selection codes in a preset order in response to an enable signal and an operation clock, and storage blocks suitable for receiving and storing the plurality of fuse status signals in a preset order in response to the selection codes.

主权项

1. A semiconductor device comprising:
a fuse array having one valid fuse set which outputs a valid fuse status signal and a plurality of fuse sets, the fuse array suitable for outputting a plurality of fuse status signals having different levels according to whether fuses in the plurality of fuse sets are cut or not; a code counter suitable for counting selection codes in a preset order in response to an enable signal and an operation clock; and a plurality of storage blocks suitable for receiving and storing the plurality of fuse status signals in a preset order in response to the selection codes, wherein the storage block comprises:
a plurality of latches suitable for storing the plurality of fuse status signals; anda plurality of selectors suitable for enabling any of the plurality of latches in response to the selection codes, wherein each of the plurality of selectors is on/off controlled in its operation in response to the valid fuse status signal regardless of values of the selection codes.
