Embodiments of the disclosure are drawn to arrangements of one or more 'cuts' or pattern of cuts in conductive structures. Wiring layers may each include a cut pattern including a set of cuts through conductive structures of the wiring layers where each of the cuts is offset from the other in a direction orthogonal to the cut. The cut pattern in a wiring layer may be orthogonal to the cut pattern in another wiring layer. In some examples, the cut pattern may be a stair-step pattern. In some examples, the cut pattern may be interrupted by other conductive structures.

Apparatuses including conductive structure layouts

Disclosed herein is a method for designing a semiconductor device, the method including: assigning a plurality of wiring tracks including first and second tracks; connecting a first data I/O circuit to a first data node of a first circuit by a first signal bus arranged on the first wiring track; connecting a second data I/O circuit to a second data node of the first circuit by a second signal bus arranged on the second wiring track when a first design mode is selected; and connecting the first data I/O circuit to a second circuit by a second signal bus arranged on the second wiring track when a second design mode is selected.

Semiconductor device having plural signal buses for multiple purposes

Embodiments of the disclosure are drawn to apparatuses and methods for trench walls including widened portions and/or conductive structures including constricted portions. The trench walls may include multiple widened portions spaced apart along a length of the trench wall in some examples. Similarly, in some examples, the conductive structures may include multiple constricted portions spaced apart along a length of the conductive structure. In some examples, the dimensions of the widened portions and/or the spacing between the widened portions may be based on properties of the trench wall.
