1. A method for reducing booting time of a wireless terminal, comprising: updating a program counter of a code region of a virtual memory; determining whether a page table contains a physical address of a first physical memory mapped by a corresponding virtual address of said virtual memory reached by said program counter; causing an abort handler to assign the physical address mapped by the corresponding virtual address to said page table if said page table does not contain the physical address mapped by the corresponding virtual address; copying code of the corresponding virtual address for performing a booting mode at the corresponding physical address of said first physical memory; and repeating the previous steps to copy all codes required for performing the booting mode to the first physical memory, wherein, during performance of the booting mode, only codes for performing the booting mode are copied to the first physical memory, and wherein, when the booting mode is started, the page table includes only address information indicating codes controlling a Memory Management Unit (MMU).
