Some FlexRIO devices contain onboard DRAM that is directly accessible from the FPGA VI. LabVIEW supports two types of DRAM interfaces: FPGA memory items and socketed CLIP. You cannot use both FPGA memory items and socketed CLIP to access the same DRAM bank in an FPGA VI. Refer to your FPGA product's Specifications document to determine the available amount of onboard DRAM for your device.
