| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We study on matrix memory using patterned ferromagnetic materials for storage elements toward highly energy-efficient computing. The ferromagnetic pattern at the intersection point of selected bit line and word line is magnetized, and the direction of magnetization corresponds to 1-bit binary information. A 3-input AND gate based on the adiabatic quantum flux parametron is used for readout, by which ultra-low energy operation is expected. We confirmed correct operation of the proposed memory cell from numerical simulation of the equivalent circuit simulating the effect of residual magnetism. We have fabricated memory cells of read-only memory using Pd0.89Ni0.11 ferromagnetic patterns in order to experimentally verify the readout operation in matrix memory. | |
