Non-volatile resistive memory cell comprising metal electrodes and a solid electrolyte between the metal electrodes
摘要:
The invention more particularly relates to a resistive memory cell comprising a first and a second metal electrodes and a solid electrolyte positioned between the first and the second metal electrodes, with the solid electrolyte comprising a commutation layer in contact with the first electrode and a dielectric layer, with said resistive memory cell being able to be electrically modified so as to switch from a first resistive state to a second resistive state (state LRS) wherein the resistance (RON) of the memory cell is at least ten times smaller than the resistance (ROFF) of the memory cell in the HRS state, in the LRS state the first electrode being so arranged as to supply metal ions intended to form at least a conductive filament through said commutation layer, with the cell being characterized in that, in the LRS state, the memory cell is conductive for a range of voltages between 0 Volts and VREST 2 .
