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.
