Integrated circuit with back-side metal line

An integrated circuit (IC) comprising:

• a first program transistor on a first side of a substrate, wherein the first program transistor includes an active area and a first gate extending along the active area;
• a first read transistor, wherein the first program transistor is coupled to the first read transistor;
• a second program transistor on the first side of the substrate, wherein the second program transistor includes a second gate extending along the active area;
• a second read transistor, wherein the second program transistor is coupled to the second read transistor;
• and
• a metal line on a second side of the substrate opposite the first side, wherein the metal line overlaps and is electrically connected to the active area, the gate of the first program transistor, or the gate of the second program transistor.

An integrated circuit (IC) comprising:

• a bit cell array, wherein each bit cell of the bit cell array comprises:
• a program transistor on a first side of a substrate, wherein the program transistor includes an active area and a gate extending along the active area;
• and
• a read transistor, wherein the program transistor is coupled to the read transistor;
• and
• a plurality of metal lines on a second side of the substrate opposite the first side, wherein the plurality of metal lines overlap and are electrically connected to one of the active areas of rows of bit cells of the bit cell array or the gates of the program transistors of columns of bit cells of the bit cell array.
