Patent ID: 7714420

Claim:
A chip arrangement comprising a first chip which has at least one first signal interface with first coupling elements arranged along a first line in a first number density and at least one second chip which has at least one second signal interface with second coupling elements arranged along a second line in a second number density, wherein the first signal interface is provided along an edge of the first chip and the second signal interface is provided along an edge of the second chip, wherein the first and second coupling elements are configured to permit contactless signal transmission between the first and second signal interfaces, wherein the first and second chips are so arranged relative to each other that coupling elements of the first and the second signal interfaces can contactlessly transmit signals with each other, wherein said edges of the first and second chips are arranged in mutually facing relationship, wherein the first and second signal interfaces have a respective first and second longitudinal extent along a respective line associated with the respective one of the first and second interfaces, the longitudinal extent of at least one of the signal interfaces along the line associated therewith being greater than a length of an overlap of the two longitudinal extents, wherein said overlap is a distance which a projection of the first longitudinal extent on to the second longitudinal extent has in common with the second longitudinal extent, wherein one of the signal interfaces has a greater number density of coupling elements than the other, and wherein the coupling elements are coils whose magnetic longitudinal axes are arranged in a horizontal plane in parallel relationship with a surface of the chip.
