WebFeb 27, 2024 · DDR4 is able to achieve even higher speed and efficiency, though keeping the prefetch buffer size 8n, same as DDR3. The higher bandwidth is achieved by sending more read/write commands per second. DDR4 standard divides the DRAM banks into two or four selectable bank groups, where transfers to different bank groups can be done faster. WebPHY Utility Bock (PUBM3) included as a soft IP utility that includes control features, such as write leveling and data eye training, and provides support for production testing of the DDR4 multiPHY DFI 3.1 compliant interface Configurable external data bus widths between 8 and 64 bits in 8-bit increments plus ECC
