DRAM Burst Length
DDR SDRAM modules provide a Burst mode that means an auto precharge function for programmable
READ or WRITE burst lengths of 2, 4 or 8 locations.
This means that if we set burst length to 8, the address bus will acesss 8 bytes each cycle to precharge,
etc.
DRAM Queue Depth:
Three options are available: 2 Level
