Title:
RESISTANCE-CHANGE NON-VOLATILE MEMORY DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/119671
Kind Code:
A1
Abstract:
A resistance-change non-volatile memory device (100) is provided with memory cells (M11, M12,...), each comprising a resistance-change element (R11, R12,...) and a current control element (D11, D12,...) connected in series. The resistance-change elements constitute a resistance-change layer interposed between a first electrode and a second electrode and provided so as to contact both electrodes. The current control elements constitute a current control layer interposed between a third electrode and a fourth electrode and provided so as to contact both electrodes. To decrease the resistance of the resistance-change elements, said elements are driven by a first LR drive circuit (105a1), via a current control circuit (105b). To increase the resistance of the resistance-change elements, the elements are driven by a second HR drive circuit (105a2). The current control circuit (105b) makes the current lower when decreasing the resistance of the resistance-change elements than when increasing the resistance thereof.
