Abstract: Compensating for offsets in buffers and related systems, methods, and devices are disclosed. An apparatus includes buffers, control circuitry, and fuses. Each of the buffers includes an output and an offset adjustment input. Each of the buffers is controllable to adjust a direct current offset of an output voltage potential responsive to an offset adjustment code provided to the offset adjustment input. The control circuitry includes sets of offset latches. The offset adjustment input of each of the buffers is operably coupled to a different one of the sets of offset latches. Each set of offset latches is configured to provide the offset adjustment code to the offset adjustment input of a corresponding buffer. The fuses are configured to provide the offset adjustment code to each of a subset of the sets of offset latches.

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.
