Part 3: DDR4 DRAM
There are two Micron DDR4 chips on the PS side of the AXU2CGA board,
which form a 32-bit data bus bandwidth and a total capacity of 1GB. There are
4 Micron DDR4 chips on the PS side of the AXU2CGB board, which form a
64-bit data bus bandwidth and a total capacity of 2GB. The maximum operating
speed of DDR4 SDRAM on the PS side can reach 1200MHz (data rate
2400Mbps). The specific configuration of DDR4 SDRAM is shown below.
Among them, U71 and U72 are only AXU2CGB mounted.

The hardware connection of DDR4 on the PS side is shown in Figure 3-1:
