Abstract
Improved random-access memory cells, complementary cells, and memory devices. The present invention provides a RRAM cell for storing information in a plurality of programmable cell states. The RRAM cell includes: an electrically-insulating matrix located between a first electrode and a second electrode such that an electrically-conductive path, extending in a direction between said electrodes, is formed within said matrix on application of a write voltage to said electrodes; an electrically-conductive component; wherein a resistance is presented by the electrically-conductive component; and wherein said RRAM is arranged such that said resistance is at least about that of said electrically-conductive path and at most about that of said electrically-insulating matrix in any of said plurality of programmable cell states.
