Abstract

A method for saving data of personal information terminal includes confirming whether cell is under low voltage state or not, confirming whether condition for storing specific data stored in volatile storage media is available or not when said cell is under low voltage state, copying specific data stored in volatile storage media and storing copied data in nonvolatile storage media when storing condition is available.

Description

technical field [0001] The invention relates to a device and a method for storing data in an electronic device, especially a device and a method for storing data in a personal information terminal PDA. Background technique [0002] Generally, since the personal information terminal has a relatively large upgrade space, there are more and more users of such terminal equipment. [0003] A personal information terminal can also be called a portable computer because it can store a large amount of data and has a very small size. During the mobile process, if the user needs to process the data, he first needs to store the required information in the terminal, and then search it out from the terminal when needed, or perform calculations. The data is stored in real time, and the processing method of this data is fast and effective. [0004] When such a personal information terminal performs a large amount of data processing, a large-capacity memory is required, and the speed of da...
