Disclosed are memory devices with high data reading and writing speed along
with capabilities for long term storage and high information density. The memory
devices allow storage of several bits of data, have fast resistance switching and
require low operating voltage but at the same time allow to combine its manufacturing
technology with the modern semiconductor manufacturing technology. An exemplary
implementation option of the memory cell contains two continuous electrodes between
which there is a multilayer functional zone consisting of one active layer, one
barrier layer and one passive layer.
