On November 2, 2022, Micron officially launched its 1β-node DRAM products and has been out to smartphone and chip platform partners for sample testing. According to Micron, 1β-node DRAM products are now ready for mass production and will be the first to adopt this new process technology for LPDDR5X mobile memory.
Smartphones are at the forefront of the industry in terms of memory specification iterations, and 1β-node LPDDR5X features more energy-efficient performance. LPDDR5X is equipped with the new JEDEC Enhanced Dynamic Voltage and Frequency Regulation Extended Core (eDVFSC) technology, which adds eDVFSC to the double frequency layer of up to 3200 Mbps for improved energy-saving control, resulting in unique based end-user mode to achieve lower power consumption, which will also enable longer smartphone life. Meanwhile, LPDDR5X mobile memory rates can be up to 8.5GB/sec for better performance. In addition, the rate and density of 1β technology will enable high-bandwidth use cases to deliver faster response and smoothness when downloading, booting, and using data-intensive 5G and AI applications simultaneously. 1β node DRAM uses Micron's proprietary multiple exposure technology and immersion lithography to achieve higher memory capacity in a smaller footprint, resulting in lower cost per unit of data. It will also enable devices with smaller form factors, such as smartphones and IoT devices, to integrate larger memory in a compact space. Micron will achieve mass production of 1β-node based DRAM products at its Hiroshima, Japan facility, and in the coming year will mass produce 1β-nodes in other applications such as embedded, data center, client, consumer, industrial and automotive, with products including display memory and high bandwidth memory.
