A programmable memory cell formed useful in a memory array having column bitlines and row wordlines. The memory cell including a breakdown transistor having its gate connected to a program wordline and a write transistor connected in series at a sense node to said breakdown transistor. The gate of the write transistor is connected to a write wordline. Further, a first sense transistor has its gate connected to the sense node. A second sense transistor is connected in series to the first sense transistor and has its gate connected to a read wordline. The second sense transistor has its source connected to a column bitline.
