Samsung chip advance paves way for phones with 4GB memory

samIn a move that should help fix a key performance bottleneck in mobile devices, Samsung announced Monday it’s developed a new 8Gb DRAM memory chip for high-end phones and tablets.

The chip uses a low-power DDR4 (Double Data Rate 4) interface that can transmit 3.2Gbps over each of its electrical connections, twice that of today’s DDR3 memory, Samsung said. And it consumes 40 percent less power.
