2.1.7 Memory Management
The high speed and large capacity RAM (MobileDDR 128MB) and FlashDisk (NAND Flash
256MB) are integrated in the terminal.
Although RAM has been used for RAM XIP (for OS), program memory (for program files) and
object store (for work area) in the past, it is unified presently to integrate FlashDisk on root folder.
Figure 2-3
Notes:
• Patch files, program files and data are not lost even if battery is exhausted. Thanks to this, it is
no longer needed to back up object store in the RAM.
• Although object store (RAM) is initialized by a full reset in the past, the functions to clear OS
and reload it are supplied.
• If user disk is formatted, registry, program files and data are initialized to the factory defaults
respectively prior to shipment.
• Although the folder named FlashDisk keeps the compatibility, but it is impossible to format
only this folder.
