Method of hibernating and pre-booting a mobile communication device to reduce apparent start up time

摘要

A mobile communication device (100) includes a volatile memory (110) and a non-volatile memory (112). Instruction code for operating the mobile communication device is permanently stored in the non-volatile memory, and copied to the volatile memory for execution. The mobile communication device enters a hibernate mode which involves shutting down most of the mobile communication device except power to the volatile memory, which allows a nearly instant apparent start up of the mobile communication device at a later time.
