DDR4 RAM operates at a voltage of 1.2 V and supports frequencies between 800 and 1600 MHz (DDR4-1600 through DDR4-3200). Compared to DDR3, which operates at 1.5 V with frequencies from 400 to 1067 MHz (DDR3-800 through DDR3-2133), DDR4 offers better performance and energy efficiency. DDR4 speeds are advertised as double the base clock rate due ...
In February 2009, Samsung validated 40 nm DRAM chips, considered a "significant step" towards DDR4 development [23] since, as of 2009, current DRAM chips were only beginning to migrate to a 50 nm process. [24] In January 2011, Samsung announced the completion and release for testing of a 30 nm 2048 MB [6] DDR4 DRAM module.
The DDR4 SDRAM is a high-speed dynamic random-access memory internally configured as 16 banks, 4 bank groups with 4 banks for each bank group for ×4/×8 and 8 banks, 2 bank groups with 4 banks for each bank group for ×16 DRAM. The DDR4 SDRAM uses an 8n prefetch architecture to achieve high-speed

Usually several memory cells share the same address. For example, a 4 bit "wide" RAM chip has four memory cells for each address. Often the width of the memory and that of the microprocessor are different, for a 32 bit microprocessor, eight 4 bit RAM chips would be needed. Often more addresses are needed than can be provided by a device.
On August 17, 2015, Rambus announced the new R+ DDR4 server memory chips RB26 DDR4 RDIMM and RB26 DDR4 LRDIMM. The chipset includes a DDR4 Register Clock Driver and Data Buffer, and it's fully-compliant with the JEDEC DDR4. [10] In 2016, Rambus acquired Semtech's Snowbush IP for US$32.5 million. Snowbush IP provides analog and mixed-signal IP ...
