Abstract
Methods and apparatus for a device that includes a circuit, such as a memory cell, and an isolation structure to electrically isolate the circuit cell. The isolation structure can include a p-type substrate, a first series of p-type material extending to the p-type substrate, and a second series of p-type material extending to the p-type substrate. The first series of p-type material, the p-type substrate, and the second series of p-type material surrounds a first side, a second side, and a bottom of the circuit cell to electrically isolate the circuit cell with continuous p-type material. In some embodiments, the first series of p-type material comprises p-type well regions. In some embodiments, the first series of p-type material comprises deep trench isolation.
