Abstract
A structure for storing a native binary code in an integrated circuit, including an array of planar MIM capacitors above an insulating layer formed above a copper metallization network, wherein at least one metallization portion is present under each MIM capacitor. The size of the portion(s) is selected so that from 25 to 75% of the MIM capacitors have a breakdown voltage smaller by at least 10% than that of the other MIM capacitors.
