Abstract
A fuse circuit of a semiconductor memory device includes: a plurality of fuse blocks. Each of the fuse blocks includes a first fuse set and a second fuse set, and is configured to output, in response to an access column address, a fuse hit signal indicating whether the access column address is programmed. The second fuse set is of a different type from the first fuse set.
Claims20
A fuse circuit of a semiconductor memory device comprising:
- a plurality of fuse blocks, each of the plurality of fuse blocks including a first fuse set and a second fuse set, and configured to output, in response to an access column address, a fuse hit signal indicating whether the access column address is programmed,
- wherein
- the second fuse set is of a different type from the first fuse set.
A fuse circuit of a semiconductor memory device comprising:
- a first fuse set configured to output a first original fuse hit signal indicating whether an access column address is programmed;
- a second fuse set configured to output a second original fuse hit signal indicating whether the access column address is programmed, the second fuse set being of a different type from the first fuse set;
- and
- a fuse router configured to route the first original fuse hit signal and the second original fuse hit signal and to output a first fuse hit signal and a second fuse hit signal.

A semiconductor memory device comprising:
- a fuse circuit configured to output a fuse hit signal indicating whether an access column address is programmed, in response to the access column address;
- and
- a column decoder configured to generate a column address by converting the access column address based on the fuse hit signal,
- wherein the fuse circuit includes a first fuse set and a second fuse set which is of a different type from the first fuse set.
