Abstract

This paper presents a wireless solid-state drive (SSD) system for future applications of large volume storage in mobile devices or data centers. The wireless interface in the developed system consists of an inductive-coupling power link with a fast transmitting power control and high-speed data links with transmission line couplers (TLCs). The wireless power link can deliver 1W from the host side to the SSD side. The full duplex wireless data interface achieved raw data rate of 1.6Gbps/link. The error correction block for NAND flash memory system can also correct the error in wireless data links. The data link has tolerance to the interference from the power link, and both the data and power links show the waterproof property of the system.
