ABSTRACT:
An improved integrated circuit cell architecture is provided for configurability between a memory cell or logic elements. The cell architecture is configured on variable layers above a first layer of metal, with the first layer of metal and layers therebelow reserved as fixed layers. By coupling a maximum of two layout cells together, a single-port or dual-port memory cell is realized. Likewise, by interconnecting transistors within a single cell or transistors among two or more cells, a logic device is realized. Within each cell, the bit lines are arranged on a layer separate from the wordlines, and extend orthogonal to each other.
