SEOUL, South Korea, Nov. 21, 2024 /PRNewswire/ -- SK hynix Inc. (or "the company", www.skhynix.com) announced today that it has started mass production of the world's first triple level cell*-based 321-high 4D NAND Flash with 1Tb capacity.
*NAND Flash products are categorized into single-, multi-, triple-, quadruple-, and penta-level cells, depending on the number of the information in the format of bit unit is stored in a cell. A bigger number of information stored means more data can be stored in the same space.
Following its previous record as the industry's first provider of the world's highest 238-layer NAND since June last year, SK hynix has become the world's first supplier of the NAND with more than 300 layers by finding a technological breakthrough for stacking. The company plans to provide the 321-high products to customers from the first half of next year.
Stacking more than 300 layers came into reality as the company successfully adopted the "3 plugs"** process technology. Known for an excellent production efficiency, the process electrically connects three plugs through an optimized follow-up process after three times of plug processes are finished. For the process, SK hynix developed a low-stress*** material, while introducing the technology that automatically corrects alignments among the plugs.
With the adoption of the same development platform from the 238-high NAND on the 321-high product, the company could also improve the productivity by 59%, compared with the previous generation, by minimizing any impacts from a process switch.
** Plug: a vertical hole through layers of substrates aimed at creating cells at once
*** Low Stress: Preventing wafer warpage by changing the material into the plugs
The latest product comes with an improvement of 12% in data transfer speed and 13% in reading performance, compared with the previous generation. It also enhances data reading power efficiency by more than 10%.
SK hynix plans to steadily expand the use of the 321-high products by providing them to the nascent AI applications, which require low power and high performance.
Jungdal Choi, Head of NAND Development at SK hynix, said that the latest development brings the company a step closer to the leadership of the AI storage market represented by SSD for AI data centers and on-device AI. "SK hynix is on track to advancing to the Full Stack AI Memory Provider by adding a perfect portfolio in the ultra-high performance NAND space on top of the DRAM business led by HBM."

In the news release, Sky Labs' Blood Pressure Monitoring Device Recognized for High Accuracy by the International Society of Hypertension, issued 24-Oct-2024 by Sky Labs over PR Newswire, we are advised by the company that there are updates to the content. The complete, corrected release follows:
CART BP Redefines Blood Pressure Monitoring with Clinically Proven Cuffless Technology
SEOUL, South Korea, Nov. 21, 2024 /PRNewswire/ -- Sky Labs, a health-tech startup based in South Korea, developed CART BP—the world's first ring-shaped, cuffless device designed for 24-hour blood pressure monitoring. Unlike conventional smartwatches, CART BP delivers more stable photoplethysmography (PPG) signals, ensuring highly accurate blood flow measurements through the finger. Wrist-based devices often struggle with accuracy due to variations in wrist size and sensor positioning. In contrast, CART BP offers multiple ring sizes for a customized fit, significantly improving measurement precision. Its accuracy has been rigorously validated in clinical trials.
One of CART BP's most significant advantages is its ability to provide continuous, cuffless blood pressure monitoring, offering greater convenience compared to traditional devices. CART BP ensures constant, unobtrusive monitoring, delivering valuable data throughout both day and night—making it an ideal tool for effective hypertension monitoring.
The ISH position paper has been endorsed by leading organizations including the World Hypertension League (WHL), the European Society of Hypertension (ESH), the Asian Pacific Society of Hypertension (APSH) and the Latin American Society of Hypertension (LASH).
According to the ISH Position Paper, "A clinical study published in 2024 indicated that the device showed good agreement with ISO requirements and strong correlation with conventional ABPM devices for daytime and nighttime BP measurements. However, calibration of the ring using cuff BP measurement was performed immediately before the accuracy testing component, and the testing was not performed in accordance with recent ESH recommendations developed specifically for cuffless devices."
Sky Labs remains committed to advancing wearable health technology, continually improving the accuracy and accessibility of blood pressure monitoring. This recognition from the ISH further solidifies CART BP's position as a leading solution in hypertension care, setting new benchmarks in patient monitoring and healthcare innovation.
About Sky Labs
Founded in September 2015, Sky Labs is a leading healthcare startup that has developed CART (Cardio Tracker), a ring-shaped medical device designed for disease monitoring using heart signals collected through optical sensors. Following this, the company developed CART BP, a cuffless, ring-shaped device that enables continuous 24-hour blood pressure monitoring, providing valuable treatment information and making a groundbreaking contribution to improving the quality of life for hypertension patients. Sky Labs has signed an exclusive domestic distribution agreement for CART BP with South Korea's Daewoong Pharmaceutical and is preparing for nationwide sales to hospitals, clinics, and general consumers.
