Abstract:
Apparatuses and methods for transmitting fuse data from fuse arrays to latches are described. An example apparatus includes: a plurality of fuse arrays, each fuse array of the plurality of fuse arrays being configured to store input data; a fuse circuit that receives the input data and provides the input data on a bus; and a plurality of redundancy latch circuits coupled to the bus, including a plurality of pointers and a plurality of latches associated with the plurality of corresponding pointers that load data on the bus. The fuse circuit may control loading of the input data by controlling a location of a pointer among the plurality of corresponding pointers responsive to the input data.
