About half a year ago, Jedec revealed the most important specifications of the DDR4 standard. The successor to the current DDR3 will be introduced at the highest official clock frequency of DDR3 memory, 1600 MHz. In 2013, DDR4 memory modules with speeds of 2400 MHz, 2667 MHz and 3200 MHz will be introduced. The voltage decreases from DDR3's 1.5V to 1.2V for the new DDR4 standard.
Samsung for one has had a DDR4 module ready for almost a year now. The standard however, is still under development, despite it being ready for production since February. Micron has announced that its ready for the launch of DDR4 memory chips. The manufacturer uses a 30 nm production process to first launch a 4 Gigabit chip with a clock frequency of up to 2400 MHz. Later this year, a 3200 MHz version should follow.
The first DDR4 DRAM memory chips that meet Jedec's latest specification have been shipped by Micron to several of its partners, allowing them to develop modules with the new DRAM chips. The first modules should be produced by the end of this year, allowing for a smooth introduction in 2013.
