(compared to DDR3's 1.5V), which reduces power usage and heat generation. Capacity Enhancements : Supports higher density chips (up to 16Gb per die) and 3DS (3D Stacking) technology for high-capacity server modules. Reliability Features : Includes advanced features like CRC (Cyclic Redundancy Check) on the data bus and Command/Address Parity to improve system stability. Signal Integrity : Introduces DBI (Data Bus Inversion) to reduce switching noise and power consumption. Who Needs This Document? Hardware Engineers
