Abstract
A solid memory may include a recording layer including Ge, Sb and Te as major components. The recording layer may include a superlattice. The recording layer may include multi-layers each having a parent phase showing a phase transformation in solid-states, the phase transformation causing change in electrical property of the recording layer. The recording layer may include an SbTelayer that includes at least one period of a first lamination of a first Te-atomic layer, a first Sb-atomic layer, a second Te-atomic layer, a second Sb-atomic layer, and a third Te-atomic layer in these order, a GeTe layer that includes at least one period of a second lamination of a fourth Te-atomic layer and a Ge-atomic layer, and an Sb layer that includes a plurality of Sb-atomic layers.
