Forming a phase change memory with an ovonic threshold switch
A phase change memory may include an ovonic threshold switch formed over an cyanic memory. In one embodiment, the switch includes a chalcogenide layer that overlaps an underlying electrode. Then, edge damage, due to etching the chalcogenide layer, may be isolated to reduce leakage current.
