Abstract

A wireless communication device including an integrated processing circuit and a first memory is provided. The integrated processing circuit includes a processing unit capable of processing a wireless communication signal and a radio frequency (RF) unit capable of performing a conversion between a radio frequency (RF) signal and a baseband signal, wherein the wireless communication signal is one or more of the RF signal and the baseband signal. The first memory is coupled to the integrated processing circuit. The first memory is capable of storing data used by the processing unit, wherein the RF unit and the first memory are packaged in a single semiconductor device.
