Abstract:
A memory cell for use in integrated circuits comprises a chalcogenide feature and a transition metal oxide feature. Both the chalcogenide feature and transition metal oxide feature each have at least two stable electrical resistance states. At least two bits of data can be concurrently stored in the memory cell by placing the chalcogenide feature into one of its stable electrical resistance states and by placing the transition metal oxide feature into one of its stable electrical resistance states.
