Abstract
Official abstract text for this publication.
The present invention relates to a layout structure and a version control circuit for integrated circuits. The layout structure for integrated circuits according to the present invention comprises a signal-supplying unit and at least a transfer cell. The signal-supplying unit is used for supplying a first signal and a second signal. The transfer cell has a plurality of metal layers interconnected. One of metal layers receives and transfers the first signal or the second signal. When changing the transfer cell to transfer the second signal instead of the first signal, the metal layers interrupt transferring the first signal but receive and output the second signal. When the circuit is revised and multiple sub-circuits as well as the transferred signal are changed, the fewest metal layers commonly adopted are used. Accordingly, the present invention can reduce effectively the number of masks, and thus reducing costs.
First claim
Opening claim text (preview).
The invention claimed is: 1. A layout structure for integrated circuits, comprising: a signal-supplying unit, receiving a first signal and converting said first signal to a second signal; and at least a transfer cell, connected electrically to said signal-supplying unit, said signal-supplying unit supplying said first signal or said second signal to said transfer cell, said transfer cell having a first transfer path and a second transfer path, each of said first transfer path an…
