5.3 Flash Memory
Non-volatile flash memory is used to store the operating firmware for the controller. The
operating firmware can be updated in the field. See CHAPTER 10 for more information.
5.4 High Speed DRAM
Because the DRAM (Dynamic Random Access Memory) is significantly faster than either
battery backed memory or flash memory, it is used to execute the operating firmware and the
user program. The contents of the DRAM are lost when power is removed and must be
refreshed from non-volatile storage during controller power up start.
