Abstract:
The present invention discloses a portable computing device (100) including a processor (102), alternate memory (106), and a DRAM memory (108). Under normal operating conditions, providing full functionality of the device, a full code instantiation in the DRAM is executed, providing operating system, user interface and application execution functionality. A reduced code instantiation (114) which duplicates certain elements of the operating system, user interface, and application code is maintained in the low power memory. When a condition occurs that dictates or allows, execution is switched from the full code instantiation to the reduced code instantiation, and the DRAM is shut off.
