Content creation and content sharing have become part of our daily lives. With modern electronics, creating and sharing content has become very convenient, but this convenience has come at a price. Devices like smartphones that enable us to easily share content, are costly and complex. Devices like USB flash drives, on the other hand, are low cost and simple. However, they do lack the convenience of smartphones when it comes to sharing content. The wireless memory presented in this thesis aims to overcome the gap between simplicity and convenience. We have designed a worlds-first wireless memory system composed of two components: a reader and a tag. The tag is a simple device to store user content while, the reader is able to access and manipulate the content on the tag. This thesis details the components required for designing and implementing a wireless memory. This knowledge is then used to build a proof-of-concept wireless memory. The resulting design is capable of wirelessly powering the tag and exchanging end-to-end data with a maximum speed of 31 kBps for reading and 27 kBps for writing. The peak power measured in the experiments was 2450mW, with a system efficiency of 57 %. The peak efficiency was measured at 69 %. Furthermore, the tag can be positioned in various orientations with respect to the reader while maintaining normal operation.
