SK Hynix Starts Production of 1anm LPDDR4 DRAM

SK Hynix has begun the mass production of the 8 Gigabit LPDDR4 mobile DRAM based on the 1anm, i.e., the fourth generation of the 10nm process technology. As the semiconductor industry classifies the 10nm DRAM products, naming them after the alphabets, the 1a technology is the fourth generation, following the first three generations of the 1x, 1y, and 1z. SK hynix plans to provide the latest mobile DRAM products to smartphone manufacturers from the second half of 2021.

SK Hynix has adopted the EUV equipment for mass production by adoption for its 1ynm DRAM production.

The company expects the new technology to bring an improvement in productivity, and further boost cost competitiveness. The company expects the 1anm technology to lead to a 25% increase in the number of DRAM chips produced from the same size of a wafer, compared with the previous 1znm node. SK hynix anticipates that the 1anm DRAM will also likely help alleviate the supply and demand conditions of the global markets following an increase in DRAM demand globally.

The company will apply its 1anm technology to its DDR5 products, the world’s first next-generation DRAM launched in October 2020, from early next year.

Cho Youngmann, Vice President at SK hynix, said that “With improved productivity and cost competitiveness, the latest 1anm DRAM will not only help secure high profitability, but also solidify SK hynix’s status as a leading technology company with early adoption of the EUV lithography technology for mass production.”

The new product stably runs 4266Mbps, the fastest transfer rate in a standard LPDDR4 mobile DRAM specification, and has reduced power consumption by 20%. It is a meaningful accomplishment for SK hynix as it aims to reduce carbon dioxide emission as part of its commitment to the environmental, social and governance (ESG) management.

The potential customers should be on alert about this product and should survey the market properly about similar products before they decide to purchase for themselves.
