Abstract
A phase change memory cell may include two or more stacked or unstacked series connected memory elements. The cell has a higher, adjustable threshold voltage. A copper diffusion plug may be provided within a pore over a copper line. By positioning the plug below the subsequent chalcogenide layer, the plug may be effective to block copper diffusion upwardly into the pore and into the chalcogenide material. Such diffusion may adversely affect the electrical characteristics of the chalcogenide layer.
