Fig.5-4:High-speed RAM operation image
The DRAM memory is used when executing high-speed RAM operation. The DRAM memory can perform
high-speed processing, which is about 1.2 times faster than the SRAM memory at maximum. (The speed
varies depending on the program contents.)
Note that robot operations, such as program execution and step operation, can be performed in the same
manner as the SRAM, but some restrictions apply. Refer to the following precautions.
