| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The experimental 4-Gbit STT-MRAM with 9F2 1T1MTJ cell of 90nm by 90nm is presented. Hierarchical bit line architecture along with two circuit techniques contributes to total 44% reduction in bank height. In order to achieve the LPDDR2 compatible specifications even in a STT-MRAM, which has a smaller page-size than DRAM, the modifications for column command timing sequence are newly proposed. The chip size of 4Gbit STT-MRAM is 107.5 mm2, which is 14 times smaller than the previous best record. | |
