| Research Abstract |
To realize digital data storage systems of extremely long lifetime, architecture for sealed wafer-scale mask ROM that is capable of contactless power delivery and contactless mutual communication has been investigated in order to enhance robustness of mask ROM device.
As for contactless power delivery, on-chip solar cell has been investigated, and "boost interleaved solar cell" has been proposed. As for contactless mutual communication, low power Tx/Rx circuits to utilize on-chip dipole antenna. NAND-type high-density low operating voltage mask ROM has been designed and evaluated. Finally, hierarchical architecture with aggressive power-gating feature has been developed.
