\u2013 DDR4 added several new power saving features compared to DDR3, including: 1. Reduced power pseudo-open drain drivers for DQ pins. 2. Additional ODT input buffer shutdown mode for power-down function. 3. Additional maximum power saving mode function. 4. Additional command address (CAL) delay.<\/p>\n
\u2013 DDR4 supports a DLL disable mode similar to the DLL disable mode in DDR3, up to 125 MHz.<\/p>\n
\u2013 DDR4 now has a test connection mode to simplify testing with a controller that supports edge scan. Designed to work with an edge scan device, CT mode is supported by all Micron 4\/8\/16Gb devices (although JEDEC only requires it for x16). The CT model allows the edge scan device to load and read a pattern from DDR4 in CT mode. DDR4 does not directly support IEEE 1149.1.<\/p>\n
\u2013 DDR4 retained the 8-bit prefetching used by DDR3; thus, BL8 is still supported.<\/p>\n
\u2013 A DDR4 block is different from a DDR3 block. However, DDR4 uses the same package dimensions and pin\/ball pitch as DDR3.<\/p>\n
\u2013 DDR3 requires VDD and VDDQ equal to 1.5 V, VREFCA equal to 0.5 x VDD, and VREFDQ equal to 0.5 x VDDQ, while DDR4 requires VDD and VDDQ equal to 1.2 V, VREFCA equal to 0.5 x VDD, and VPP equal to 2.5 V.<\/p>\n
\u2013 DDR4 still uses the VTT termination on the data bus for good signal quality, however it uses pseudo-open drain drivers for lower switching current compared to full push-pull drivers.<\/p>\n
\u2013 DDR4 does not require an external VREFDQ, but provides an internally generated VREFDQ that requires calibration by the DRAM controller.<\/p>\n
\u2013 DDR4 is backward compatible with DDR3-1333.<\/p>\n
For systems that don't need a speed increase above DDR3-1333 and DDR3-1600, DDR4 can support these slow bandwidth requirements with significantly lower power requirements.<\/p>\n
