I wonder how fast I can read from a DDR SDRAM (known as DDR1) clocked at 200MHz. The controller will be implemeted on an FPGA.
I have 8 bit data interface to the DDR. Each data pin reached 400Mbps. Therefore the total throughput is 3.2Gbps = 400MBps. However there will be an overhead for read commands to the DDR.
Including those what is the practical maximum READ throughput I can reach?
