Memory cards are widely used in electronic systems to expand internal storage area or are used as detachable media to carry data. Although cloud computing has recently drawn attention, data transfer consumes significant power (e.g., 1% battery charge of a smartphone when 10 pictures are transferred through WLAN), making local memory card storage still attractive in mobile devices. As storage capacity increases, the I/O speed should also increase accordingly. However, conventional memory cards require strong ESD protection, limiting high-speed data transfer. A non-contact memory card [1] is one of the solutions to this problem. No signal terminals are exposed for mechanical contact, which relaxes ESD constraints. A data transfer rate of 6Gb/s/ch by inductive coupling
