South Korean memory maker SK hynix today announced that it has delivered samples of what it claims is the world’s fastest mobile DRAM, and expressed belief that it will eventually be used in more. of applications.

The Low Power Double Data Rate 5 Turbo, or LPDDR5T, is 13% faster than the LPDDR5X that the chip shop revealed last November – hence the word “turbo” appended to its name. The turbo version tops out at 9.6Gbps on a 10nm process, compared to the previous iteration’s 8.5Gbps on a 12nm process.

According to SK hynix’s canned statement, a 16GB multi-chip package – like the ones shown as examples – can process 77GB of data per second, or fifteen Full HD movies in one second. A little less if one of them is Avatar.

In accordance with JEDEC guidelines, LPDDR5T operates between 1.01 and 1.12 V, meeting expectations of being both fast and requiring incredibly low power to operate.

Like its predecessor, the DRAM product has been processed using High-K Metal Gate (HKMG), which is intended to prevent current leakage and improve capacity. SK hynix is ​​the first memory manufacturer to use the process in a mobile product.

SK hynix plans to begin mass production of the product using its advanced 10nm process – called 1anm – in the second half of 2023. Its commercialization for the product raises hopes that it will eventually move from mobile devices to other loads work – at least until LPDDR56 dedicated to these tasks emerges.

“The IT industry foresees an increasing demand for memory chips with advanced specifications as the 5G smartphone market develops further. In this trend, SK hynix expects the application of LPDDR5T to expand beyond- beyond smartphones to artificial intelligence (AI), machine learning, and augmented/virtual reality (AR/VR),” a spokesperson explained.

Top products from competitors such as Samsung and Micron still meet the lower LPDDR5X specification.

Samsung said its LPDDR5X with its speed of 8.5Gbit/sec, released last November, also suitable for AI and even automobiles. Micron released samples of its LPDDR5X, also at 8.5 Gbps, around the same time.

SK hynix experienced sharp profit in late 2023 as it awaits the launch of 238-layer RAM products that are expected to change things this year. With not one but two new DRAMs released since its disastrous third-quarter earnings call, the announcement of 238-layer products could turn the tide on profitability. ®
