\u00b7 Product compatibility test with global smartphone manufacturer underway<\/strong>
\n\u00b7 Secures top-notch competitiveness in price, quality for NAND product<\/strong>
\n\u00b7 Expects NAND technology competitiveness to drive earnings rebound in 2H<\/strong><\/div>\n

Seoul, June 8, 2023<\/strong>
\nSK hynix Inc. (or \u201cthe company\u201d, www.skhynix.com<\/a><\/span>) announced today that it has started mass production of its 238-layer 4D NAND Flash memory, following the development in August 2022, and that product compatibility test with a global smartphone manufacturer is underway.<\/p>\n

\u201cSK hynix has developed solution products for smartphones and client SSDs which are used as PC storage devices, adopting the 238-layer NAND technology, and has moved into mass production in May,\u201d the company said. \u201cGiven that the company secured world-class competitiveness in price, performance and quality for both 238-layer NAND and the previous generation 176-layer NAND, we expect these products to drive earnings improvement in the second half of the year.\u201d<\/p>\n

The 238-layer product \u2013 the smallest NAND in size \u2013 has a 34% higher manufacturing efficiency compared to the previous generation of 176-layer, resulting in a significant improvement in cost competitiveness.<\/p>\n

Besides, with a data-transfer speed of 2.4Gb per second, a 50% increase from the previous generation, and approximately 20% increase in read and write speed, the company is confident that it will be able to deliver an improved performance to the smartphone and PC customers using this technology.<\/p>\n

Once the product compatibility test with the global smartphone manufacturer is completed, SK hynix will begin supplying the 238-layer NAND product for smartphones, and expand the technology across its product portfolio such as PCIe 5.0*<\/sup> SSDs and high-capacity server SSDs going forward.<\/p>\n

*<\/sup>PCIe 5.0<\/strong>: PCIe(Peripheral Component Interconnect Express) is a serial-structured high-speed input\/output interface used in the main boards of digital devices, with PCIe 5.0 doubling the data rate to 32GT\/s(Gigatransfer per second) from PCIe 4.0<\/p>\n

\u201cWe will continue to overcome NAND technology limitations and increase our competitiveness so that we can achieve a bigger turnaround than anyone else during the upcoming market rebound,\u201d said Jumsoo Kim, Head of S238 NAND at SK hynix.<\/p>\n
