Samsung has announced an 8 GB LPDDR4 DRAM package intended for smartphones and tablets, using four 16 Gb (2 GB) chips manufactured on a 10nm-class process (probably 18nm):

Samsung this week announced its first LPDDR4 memory chips made using its 10nm-class DRAM fabrication technology. The new DRAM ICs feature the industry's highest density of 16 Gb, are rated to run at 4266 MT/s data rate, and open the door to more mobile devices with 8 GB of DRAM.

Earlier this year Samsung started to produce DDR4 memory using its 10nm-class DRAM manufacturing process (which is believed to be 18 nm) and recently the firm began to use it to make LPDDR4 memory devices, just as it planned. The thinner fabrication technology allowed Samsung to increase capacity of a single LPDDR4 DRAM IC to 16 Gb (up from 12 Gb at 20nm introduced in August, 2015) while retaining a 4266 MT/s transfer rate.

The first product to use the 16 Gb ICs is Samsung's 8 GB LPDDR4-4266 mobile DRAM package for smartphones, tablets, and other applications that can use LPDDR4. The device stacks four memory ICs and provides up to 34 GB/s of bandwidth when connected to an SoC using a 64-bit memory bus. The 8 GB DRAM package comes in a standard 15 mm x 15 mm x 1 mm form-factor, which is compatible with typical mobile devices, but Samsung can also make the package thinner than 1 mm to enable PoP stacking with a mobile application processor or a UFS NAND storage device.

The press release confirms the high data rate:

The new 8GB LPDDR4 operates at up to 4,266 megabits per second (Mbps), which is twice as fast as DDR4 DRAM for PCs working typically at 2,133 Mbps per pin. Assuming a 64 bit (x64) wide memory bus, this can be viewed as transmitting over 34GBs of data per second.

Tune in next year when I post about Samsung putting 12 GB of RAM in smartphones.
