Micron Unveils 1β (1-beta) DRAM Process Node, LPDDR5X-8500 Memory

Micron announced Tuesday Next Generation 1β (1-beta) Manufacturing Technology for DRAM (opens in new tab) (Dynamic Random Access Memory). The new node will allow Micron to reduce DRAM costs while improving power efficiency and performance. 1β (1-beta) will be the company’s last his DRAM manufacturing process that relies on deep ultraviolet (DUV) lithography and does not use extreme ultraviolet (EUV) tools.

Micron’s 1β manufacturing process uses the company’s second-generation High-K Metal Gate (HKMG), increasing bit density for 16Gb memory dies by 35% and improving power efficiency by 15% compared to similar DRAM devices It is said to let On the company’s 1α node. New manufacturing techniques are especially useful for high-capacity DDR5 and LPDDR5X chips for mobile, server and desktop applications.

Unlike rivals Samsung and SK Hynix, Micron currently does not use EUV tools and must rely on various multi-patterning techniques to keep its DRAM cells small.

Thy Tran, Micron’s vice president of DRAM process integration, said: “1β also comes with new processes, materials and advanced equipment to advance memory cell integration so that memory cell arrays can be shrunk. […] To maximize all technological advantages and design innovations, both the memory cell height and the rest of the circuitry within the die are aggressively scaled to save space and achieve the smallest possible size for a given density. Die. Optimized for increased power and performance. ”

The first product Micron will create using the cutting-edge node is 16Gb LPDDR5X-8500 memory, but eventually the company plans to start using the node for other products. The 16Gb LPDDR5X chip is said to offer enhanced Dynamic Voltage and Frequency Scaling Enhanced Core (eDVFSC) voltage control technology for power saving.

LPDDR5X memory was designed to improve the performance of a wide variety of bandwidth-hungry applications, such as PC-class system-on-chips and artificial intelligence (AI) accelerators, as well as mobile applications such as tablets and smartphones. .

According to Micron, Micron’s 16Gb LPDDR5X-8500 memory and its 1β manufacturing process are ready for mass production. The company is currently shipping samples of his LPDDR5X-8500 DRAM to interested parties and plans to start mass production of these ICs once they pass the qualification process.
