Method for initializing a ram of an electronic device

Abstract

Disclosed is a method for initializing a RAM of an electronic device capable of reducing a time consumed for a RAM initializing process to rapidly make progress a boot-up process of an electronic device such as mobile communication terminal. The method comprises steps of filling a zero-initialize region of the RAM with ‘0’; and copying a code of a ROM of the electronic device to a code region of the RAM, wherein in the step of filling the zero-initialize region with ‘0’, if one or more addresses of the N addresses constituting the zero-initialize region of the RAM are not filled with ‘0’, the N addresses are sequentially filled with ‘0’, and in the copying step, if the code is not copied to one or more addresses of the N addresses constituting the zero-initialize region of the RAM, the code of the ROM is sequentially copied to the N addresses.
