Abstract:
A memory cell including a phase-change material may have reduced leakage current. The cell may receive signals through a buried wordline in one embodiment. The buried wordline may include a sandwich of a more lightly doped N type region over a more heavily doped N type region over a less heavily doped N type region. As a result of the configuration of the N type regions forming the buried wordline, the leakage current of the buried wordline to the substrate under reverse bias conditions may be significantly reduced.
