SK Hynix releases big news: 238-layer 4D NAND flash memory is mass-produced, and mobile phone tests show that the speed is increased by 50%
News on June 8, South Korean memory manufacturer SK Hynix announced today that they have begun mass production of 238-layer 4D NAND flash memory chips. It is reported that SK Hynix is conducting product verification with overseas smartphone manufacturers.
SK hynix said that they have successfully developed client SSD (Client) suitable for smartphones and personal computers (PC). SSD) solution and began mass production in May. Whether in 176-layer or 238-layer products, SK hynix has ensured world-leading competitiveness in terms of cost, performance and quality. According to the editor's understanding, the 238-layer NAND flash memory chip is currently one of the smallest chips in the world. Compared with the previous generation of 176-layer chips, its production efficiency has increased by 34%. The data transmission speed of this new product reaches 2.4Gb (gigabit) per second, which is 50% faster than the previous generation, and the read and write performance has also been improved by about 20%.
SK Hynix said that after completing product verification with smartphone manufacturers, they will first supply 238-layer NAND flash memory to the mobile device market chips, and subsequently expanded their application scope to include PCIe-based 5.0 PC solid-state drive (SSD) and data center-level high-capacity SSD products.
SK Hynix introduced 4D technology in 2018, in which 96-layer NAND flash memory uses charge trapping technology (CTF) and PUC (Peri. Under Cell) technology. According to the editor's understanding, compared with 3D technology, 4D architecture has the advantages of smaller unit area and higher production efficiency. SK hynix expects these new products to play a positive role in promoting the company's performance in the second half of the year.
The above is the detailed content of SK Hynix releases big news: 238-layer 4D NAND flash memory is mass-produced, and mobile phone tests show that the speed is increased by 50%. For more information, please follow other related articles on the PHP Chinese website!

Sources say SK Hynix's five-layer stacked 3D DRAM memory yield has reached 56.1%
Jun 24, 2024 pm 01:52 PM
According to news from this website on June 24, Korean media BusinessKorea reported that industry insiders revealed that SK Hynix published the latest research paper on 3D DRAM technology at the VLSI 2024 Summit held in Hawaii, USA from June 16 to 20. In this paper, SK Hynix reports that its five-layer stacked 3D DRAM memory yield has reached 56.1%, and the 3D DRAM in the experiment exhibits similar characteristics to current 2D DRAM. According to reports, unlike traditional DRAM, which arranges memory cells horizontally, 3D DRAM stacks cells vertically to achieve higher density in the same space. However, SK hynix
Sources say Samsung Electronics and SK Hynix will commercialize stacked mobile memory after 2026
Sep 03, 2024 pm 02:15 PM
According to news from this website on September 3, Korean media etnews reported yesterday (local time) that Samsung Electronics and SK Hynix’s “HBM-like” stacked structure mobile memory products will be commercialized after 2026. Sources said that the two Korean memory giants regard stacked mobile memory as an important source of future revenue and plan to expand "HBM-like memory" to smartphones, tablets and laptops to provide power for end-side AI. According to previous reports on this site, Samsung Electronics’ product is called LPWide I/O memory, and SK Hynix calls this technology VFO. The two companies have used roughly the same technical route, which is to combine fan-out packaging and vertical channels. Samsung Electronics’ LPWide I/O memory has a bit width of 512
Hynix is the first to demonstrate UFS 4.1 flash memory: based on V9 TLC NAND particles
Aug 09, 2024 pm 03:33 PM
According to news on August 9, at the FMS2024 Summit, SK Hynix demonstrated its latest storage products, including UFS4.1 universal flash memory that has not yet officially released specifications. According to the official website of the JEDEC Solid State Technology Association, the latest UFS specification currently announced is UFS4.0 in August 2022. Its theoretical interface speed is as high as 46.4Gbps. It is expected that UFS4.1 will further improve the transmission rate. 1. Hynix demonstrated 512GB and 1TBUFS4.1 general-purpose flash memory products, based on 321-layer V91TbTLCNAND flash memory. SK Hynix also exhibited 3.2GbpsV92TbQLC and 3.6GbpsV9H1TbTLC particles.

According to the official website of the JEDEC Solid State Technology Association, the latest UFS specification currently announced is UFS4.0 in August 2022. UFS4.0 specifies a theoretical interface speed of up to 46.4Gbps for each device, and USF4.1 is expected to further improve the transmission rate. ▲JEDECUFS specification page SK Hynix demonstrated two UFS4.1 general-purpose flash memories with capacities of 512GB and 1TB respectively, both based on the 321-layer stacked V91TbTLCNAND flash memory.
It is reported that SK Hynix and Samsung Electronics have significantly expanded production of HBM memory this year, but the current yield rate is only 65%
Mar 05, 2024 pm 04:00 PM
According to news from this site on March 4, Korean media DealSite reported that SK Hynix and Samsung Electronics will significantly expand production of HBM memory this year. However, HBM memory has problems such as low yield, making it difficult to keep up with the demand related to the AI market. As a hot commodity in the AI semiconductor market, HBM memory uses wafer-level packaging (WLP): multi-layer DRAM memory wafers are connected to the basic wafer through TSV through silicon holes. A problem with one of the DRAM layers means that the entire HBM stack of scrapping. ▲HBM memory structure diagram. Image source: SK Hynix takes an 8-layer stacked product as an example. If the yield rate of each stack is 90%, then the yield rate of the overall HBM stack is only 43%, and more than half of the DRAM is discarded. And when HBM reaches the 12th floor,
