SK Hynix introduces the fastest memory for smartphones and more – LPDDR5T with a speed of 9.6 Gb/s

Just two months after announcing the world’s fastest LPDDR5X memory for mobile devices, SK Hynix is ​​already there is faster LPDDR5T memory. This memory will be the last stage in preparation for the transition to LPDDR6 chips, and to emphasize the exceptionally high quality of the new product, the new LPDDR5 modification received the prefix “T”, which stands for Turbo.

LPDDR5T will be 13% faster than LPDDR5X memory, which is required by new mobile devices ranging from smartphones to AR/VR headsets and other devices, as well as artificial intelligence applications and especially edge AI solutions in the form of robots and other solutions will.

As you know, the transmission speed of LPDDR5X chips, launched in October last year, reaches 8.5 Gbps per contact. LPDDR5T memory speed is claimed to be 9.6Gbps per contact. At the same time, chip consumption increased slightly, which indicates an increase in energy efficiency.

SK Hynix intends to start mass production of LPDDR5T chips in the second half of this year. The products are immediately in demand, since samples of microcircuits have already been sent to numerous customers of the company for testing. LPDDR5T memory is likely to be featured in finished products at CES 2024 and will appear on general sale in the winter and spring of next year.

LPDDR5T microcircuits are manufactured using the fourth generation of 10nm class process technology (under the designation SK hynix – 1anm). For the production of key transistors of memory cells, the so-called HKGM (High-K Metal Gate) process technology is used, which is well known to us from the production of processors. The metal gates of transistors are insulated with a high-dielectric film that reduces leakage currents, which increases transistor performance and reduces their consumption.

LPDDR5T chips operate in the ultra-low-voltage range specified by the JEDEC committee for LPDDR5 memory: from 1.01 to 1.12 V. Before the appearance of LPDDR6 memory, a faster product of the LPDDR5 generation. However, it will be interesting to see how Samsung will react to the SK hynix initiative in the form of the “Turbo” label?
