Operational DDR4 SDRAM prototypes appear at ISSCC

As reported this week by several Web sites including Techeye.net, Samsung and Hynix both demonstrated working prototypes of DDR4 SDRAM at the ISSCC conference in San Francisco this week. The Samsung and Hynix DDR4 memories were manufactured in 30nm and 38nm process technologies respectively but production chips will use smaller lithographies when the memories go into volume production later this year. According to the Techeye article you can expect to see Micron, Elpida, and Nanya enter the DDR4 fray later this year as well.
