SK Hynix believes in 600-layer 3D NAND flash

It’s not just Intel’s CEO who spoke about the company’s plans this week. Almost simultaneously with the keynote speech at the IEEE International Symposium, SK Hynix CEO Seok-Hee Lee made a speech. He shared his vision of the future in relation to the products manufactured by SK Hynix, that is, to memory chips.

The head of SK Hynix presented several conceptual developments that the company is working on right now. They refer to 3D NAND and DRAM memory.

If earlier the company believed that the scaling potential of 3D NAND is limited to about 500 layers, then recent studies allow the manufacturer to hope to master the production of 600-layer 3D NAND memory. Let us clarify that this is a matter for the distant future. So far, the company has managed to manufacture and test 176-layer 3D NAND chips with a density of 512 Gbps. A further increase in the number of layers requires the solution of several technical problems, including the improvement of dielectric materials and an increase in the uniformity of the formed layers.

A similar situation is observed in the development of DRAM. The manufacturer associates a further increase in density with the transition to EUV lithography, which will overcome the limitations of modern technology. At the same time, SK Hynix is ​​trying to reduce the thickness of the dielectric layer, develop new insulating materials with high dielectric constant and conductors with reduced resistance.

Not a trace remained of $ 66,000. Bitcoin fell, followed by Ethereum

The week began for the main cryptocurrencies of the world with a rise in price and the establishment of new price highs, and ends with a fall, and quite noticeable. Over the course of a day, Bitcoin loses about 4.5% of its value, and as a result, for 1 BTC now they give not $ 66,000, but about $ 60,500.

After Bitcoin began to fall, Ethereum was still holding, but its rate had already gone down too, dropping below the psychological mark of $ 4,000. Analysts believe that such a fall in cryptocurrencies is due to their sell-off on the part of investors – they are fixing profits against the backdrop of a strong growth in value that has been observed since the end of September. This means that after the current correction, Bitcoin may rush to new heights, but whether altcoins will follow it is a big question.

Interestingly, against the background of a decrease in quotations of other cryptocurrencies from the Top 10, Solana feels very confident: it grew by almost 6% per day, and by almost 25% in a week.
