Abstract
A memory integrated circuit has memory arrays that are vertically layered. These memory arrays include word lines and bit lines. Intersections between the word lines and the bit lines include a diode and a memory state storage element. The diode and the memory storage element are connected in between a word line and a bit line. The diode at the intersections includes a first diode node and a second diode node. Various aspects of the memory integrated circuit are electrically interconnected in various ways, such as corresponding word lines, corresponding first diode nodes, or corresponding second diode nodes of different memory arrays being electrically interconnected. Various aspects of the memory integrated circuit are isolated in various ways, such as word lines, first diode nodes, or second diode nodes of different memory arrays being isolated.
