Abstract: The invention relates to a method for recording a memory parameter and a method for optimizing a memory. In the invention, adjusted enhancement parameter data can be stored in a non-volatile memory of a memory module. Then, the setting value of a parameter of a memory module is portable, and users can write the needed setting value of the memory parameter into the non-volatile memory of the memory module. In other words, in the invention, no matter whether the memory module is applied to the same computer or not, the enhancement parameter data can be applied to prevent the users from repeatedly setting the memory parameter of the memory module in different computers.

Abstract: An information processing apparatus having a resume function which can maintain the security even when a plurality of users commonly use the apparatus. A work state at a power-off time of the apparatus is preserved together with a work state name including a user's ID in a different area in a plurality of preservation areas for resume function on a main memory for each user. When a power source is again turned on, data in the preservation area corresponding to the user's ID is used to reproduce the work state of the user at the power-off time. The work preservation areas can be provided on a file server apparatus in a network not needing battery back-up. When the information processing apparatus is used, a work state at a power-off time can be independently preserved and reproduced for each user.
