A "smart" memory card architecture and interface provides significantly increased performance, in part, by using fast access dynamic random access memory (DRAM) technologies which allows up to 8-byte data transfers from the memory card every 27ns after the initial access. The 27ns transfer rate includes...http://www.google.de/patents/US4888773?utm_source=gb-gplus-sharePatent US4888773 - Smart memory card architecture and interface
