| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have developed a new magnetic random access memory with current-induced domain wall motion (DW-motion MRAM) using perpendicular magnetic anisotropy materials. We confirmed its potentials of 0.2-mA and 2-ns writing with sufficient thermal stability, and also demonstrated good memory operations. The cell size of this MRAM was estimated to be around 0.1 um2. The obtained properties indicate that this MRAM can replace conventional high-speed embedded memories currently used in system LSI such as eSRAM and eDRAM. | |
