1.1.1 Flash memory
The flash memory stores all data that should be preserved when the device is powered down. The flash
memory is designed as a combination of two flash chips (Intel) with a total capacity of 512 MB.
1.1.2 The RAM memory
RAM technology is installed on the processor module as an internal memory. The RAM is divided into
several areas:
Kernel program code
This is where the kernel code is stored that is extracted by the flash when the device is booted. The system’s
response speed is therefore faster because the RAM (instead of the flash) is used to execute the kernel.
Registry
The registry occupies a small space on the RAM. It is used during system runtime and can be persisted
triggered by Start
Programs
SysTools
Save Registry. Without persisting the registry, changes made
during runtime will be lost. This significantly improves the stability of the entire system.
Storage Memory
This RAM area is allocated for volatile file storage. It is stored as a file system layer on directories defined
specifically for the device (see Chapter 1.1.3).
Program Memory
Internal memory that can be used by programs. Program memory works like the RAM on desktop PCs.

Note
To set the division between storage memory and program memory, go to
Start
Settings
Control Panel
System
Memory.
The change cannot be persisted by saving the registry. Go to
Start
Programs
ACD
StartConfig and with the System memory division option
define the amount of storage memory that should be automatically allocated when
the device is booted
(in KB).
