PERIPHERAL MEMORY DEVICE FOR A WIRELESS PHONE AND METHODS OF IMPLEMENTING AND USING SAME

摘要

A wireless telephone unit includes a serial interface to which memory stick units can be selectively connected. Each memory stick unit includes a serial interface, data register and memory unit. By using one or more memory sticks for auxiliary data storage, the wireless telephone unit can provide a host of functions not available with conventional wireless phones. For example, the wireless telephone unit and memory stick combination may provide expanded contact and schedule information storage that is easily transferred between phones. The wireless telephone unit may also become a personal audio device providing music or other audio programming that is recorded on a memory stick unit.
