ABSTRACT:
A programmable via structure that includes at least two phase change material vias each directly contacting a heating element, the via structure further including a first terminal in contact with a first heating element portion, a second terminal in contact with a second heating element portion, a third terminal in contact with one of the vias, and a fourth terminal in contact with another one of the vias; a first circuit block in contact with one of the third and fourth terminals; a second circuit block in contact with the third or fourth terminal not contacting the first circuit block; a source region of a first transistor in contact with one of the first and second terminals; and a drain region of a second transistor in contact with the first or second terminal that is not contacting the source region of the first transistor.
