Standard RAM

(1) Definition
This memory is for using file registers, local devices, and sampling trace files without a memory card.
Storing the file registers in the standard RAM allows fast access as data registers do.
If the size of files to be stored exceeds the standard RAM capacity:
• store the files in the memory card, or
• reduce the number of points of the file register, local device, or sampling trace.
Note when file registers are stored in the memory card, the access speed will be slower than when they are
stored in the standard RAM.
