    摘要: Building programmable resistive devices in contact holes at the crossover of a plurality of conductor lines in more than two vertical layers is disclosed. There are plurality of first conductor lines and another plurality of second conductor lines that can be substantially perpendicular to each other, though in two different vertical layers. A diode and/or a programmable resistive element can be fabricated in the contact hole between the first and second conductor lines. The programmable resistive element can be coupled to another programmable resistive device or shared between two programmable devices whose diodes conducting currents in opposite directions and/or coupled to a common conductor line. The programmable resistive memory can be configured to be programmable by applying voltages to conduct current flowing through the programmable resistive element to change its resistance for a different logic state.
