Abstract

A wireless communication device including an integrated processing circuit, a first memory and a testing circuit 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 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. The testing circuit is coupled to the first memory, and is capable of testing the first memory for determining if the first memory is an effective memory. The RF unit is put in a first package, the first memory is put in a second package, and the first package and the second package are packaged in a single device.
