Abstract

A highly reliable wireless solid-state drive (SSD) system for future applications of large volume storage is presented. The wireless interface in the system consists of an inductively coupled power link with fast transmission power control and high-speed data links using transmission line couplers (TLCs). The wireless power link can deliver 1 W from the host to the SSD. The full duplex wireless data interface achieves raw data rate of 1.6 Gb/s. The reliability of the wireless interface is studied though simulation analysis and experiments. The error correction block for the NAND flash memory system can also correct errors in the wireless data links, allowing the requirements for the PHY layer to be relaxed. The error correction code is discussed, including optimization by analyzing the error bits on the wireless data links. The experimental results confirmed strong tolerance to the interference from the power link on the wireless data link, and the water proof property of both the data and power links.
