Claim 10:
11. A RRAM structure, comprising:
a substrate having at least one fin structure;
a high voltage transistor comprising:
a drift region located in the fin structure;
a gate structure located on the fin structure and on a portion of the drift region;
a dummy gate structure located on the fin structure and on the drift region;
a source region and a drain region located in the fin structure on two sides of the gate structure and the dummy gate structure, wherein the drain region is located in the drift region; and
an isolation structure located in the drift region and between the gate structure and the dummy gate structure; and

a RRAM cell comprising a first electrode, a resistive switching layer, and a second electrode sequentially located on the drain region, wherein the RRAM cell is electrically connected to the high voltage transistor.
