Samsung will begin mass production of LPDDR5-5500 for smartphones this month. The stacking of eight 12 Gbit dies is expected to result in DRAM memory chips with a capacity of 12 GigaBytes. Besides smartphones, IoT as well as artificial intelligence (AI) is the target market.

Only a few weeks after the explanation for the production of the first 6-Gbit chips and later also 8-Gb-Dies this Samsung with a doubling of the capacity quickly after. Today, the manufacturer is speculating more closely on a product, at the beginning of the month, this was rather an overview of what with LPDDR5 everything will be possible. That's why Samsung today clearly speaks of 5,500 MT / s as a transfer rate, not more up to 6,400 MT / s than the maximum possible.

LPDDR5 and DDR5 have only conditional commonality as a memory standard. Because the low-power rail in RAM has always been independent and in some cases significantly more advanced than classic RAM. LPDDR4 (X) was already officially certified up to 4,266 Mbit / s at very low voltages. LPDDR5 raises the effective data rate by a further 50 percent to a maximum of 6,400 Mbit / s, which requires a voltage of only 1.1 volts. The even more power-efficient modes with 1.05 volts voltage release a maximum of 5,500 Mbit / s to start – exactly on this Samsung is primarily set. The chips are made in the second generation of the 10nm class, called 1y in the industry.

Probably not seen until 2020 in the trade

With such announcements Samsung shoots again very early on the market, the manufacturer boasts itself with the fact that only five months between 12 Gbit chips after LPDDR4X standard and now LPDDR5 lie. Until such memory chips are really on the market or are installed in the first devices in a larger series, it should be the year 2020. Today, Samsung itself is talking about not moving production to its large production site Pyeongtaek in South Korea until next year, if demand rises accordingly. Then a 16-Gigabit-Die should be launched, which can logically offer 16 GB of LPDDR5 memory for smartphones.
