Abstract
A semiconductor device according to the present invention includes: a semiconductor chip; and memory and logic sections formed on the semiconductor chip. The memory section includes: an array of memory cells; a sense amplifier circuit; and memory interconnects respectively provided in a number n (where n is a positive integer) of interconnect layers. The logic section includes logic circuits having logic interconnects respectively provided in a number n+m (where m is a positive integer) of interconnect layers. A metal layer is formed in one of (n+1)th to (n+m)th interconnect layers, covers the array of memory cells and supplies a predetermined potential to the memory section.
