Distributed signal transmission to an integrated circuit array

摘要

In a dynamic random access memory (10) that includes a cell array area (12) and at least one peripheral array area (14), a plurality of sense amplifier banks (20) are arranged in rows. A plurality of elongate longitudinal signal conductors (92) are formed over the cell array area (12) to intersect each of the rows. Each row has at least one transverse signal conductor (98) that is coupled to at least some of the longitudinal signal conductors (92). Inputs of the sense amplifiers (30) in the row are coupled to the transverse signal conductor (92) for receiving the global signal. A signal driver circuit (124-130) is formed in the peripheral area (14), with the longitudinal conductors (98) coupled to outputs of the signal driver circuit (124-130).
