Abstract :
We have developed a new magnetic random access memory with current-induced domain wall (DW) motion (DW-motion MRAM). We confirmed its potential of 0.1-mA and 2-ns writing with sufficient thermal stability. The obtained properties indicate that this MRAM can replace conventional high-speed embedded memories.
