Figure 2.2 shows a block diagram of the DDR4 SDRAM interface.
The DDR4 SDRAM is controlled by the DDR3L/DDR4 SDRAM Memory Controller (MEMC) that is with built-in to
the RZ/G2UL. This interface supports up to DDR4-1600 SDRAM, a data bus width of 16-bit and inline ECC.
This interface complies with JEDEC STANDARD JESD79-4C.
