Part 1.3: DDR4 DRAM

The AXKU062 FPGA development board is equipped with four Micron 1GB DDR4
chips, model MT40A512M16LY-062EIT. Four DDR4 SDRAMs form a 64-bit bus width.
Because four DDR4 chips are connected to the FPGA, the DDR4 SDRAM can run at
speeds up to 1200MHz, and four DDR4 memory systems are directly connected to
the BANK44, BANK45, and BANK46 interfaces of the FPGA. The specific configuration
of DDR4 SDRAM is shown in Table 3-1.
Bit Number
U45,U47,U48,U49
The hardware design of DDR4 requires strict consideration of signal integrity. We
have fully considered the matching resistor/terminal resistance, trace impedance
control, and trace length control in circuit design and PCB design to ensure
high-speed and stable operation of DDR3.
The hardware connection mode of FPGA and DDR4 DRAM is shown in Figure
