Samsung starts churning out 20nm 4Gb LPDDR3

Performance comparable to PC DRAM

Samsung has started producing 4Gb low-power DDR3 chips using its 20nm manufacturing process. The new mobile DRAM is said to deliver comparable performance to standard DRAM used in mainstream PCs.

The new chips can sustain transfer speeds of up to 2,133 megabits per second, more than double the performance of LPDDR2 chips, which maxed out at 800Mbps. Compared to existing 30nm-class LPDDR3, the new chips offer 30 percent more performance with a 20 percent saving in power consumption.

Using the new chips OEMs will be able to cram 2GB of RAM in a single 0.8mm high package, Samsung said.
