The DDR4 memory standard, which the Joint Electronic Devices Engineering Council (JEDEC) expects to OK this summer, represents a doubling of performance over its predecessor and a reduction in power use by 20% to 40% based on a maximum 1.2 volts of power use.
"It's a fantastic product," said Mike Howard, an analyst with market research firm IHS iSuppli. "Increasing the amount of memory and the bandwidth of that memory is going to have huge implications."
DDR4's significant reduction in power needs means that relatively low-priced DDR memory will, for the first time, be used in mobile products such as ultrabooks and tablets, according to Howard.
Today, mobile devices use low-power DDR (LPDDR) memory, the current iteration of which uses 1.2v of power. The next generation of mobile memory, LPDDR3, will further reduce that power consumption (probably by 35% to 40%), but it will likely cost 40% more than DDR4 memory, said Howard. (LPDDR memory is more expensive to manufacture.) Read More
