Micron Technology is planning to sell its chip factory in Lehi, Utah as it stop making 3D Xpoint memory chip it jointly developed with Intel nearly a decade ago.
Lehi is Idaho-based Micron’s only factory making 3D Xpoint memory, a form of memory chip that aimed to find a price-to-performance sweet spot between the two dominant forms of memory chip: DRAM, which is fast but pricey, and NAND, which is slower but cheaper.
The factory will be sold in a transaction expected to close by the end of this year, Reuters reported.
Micron said it will increase investment in new memory products that leverage the Compute Express Link (CXL). Micron will stop development of 3D XPoint and shift resources to focus on accelerating market introduction of CXL-enabled memory products.
Micron introduced its first products based on the technology in 2019 with a set of solid-state drives aimed at data center customers.
Sumit Sadana, Micron’s chief business officer, told Reuters in an interview that they received a tepid response from customers because they would have had to re-write large portions of their software to take advantage of the new type of memory.
Low demand means Micron cannot scale up manufacturing to a high enough volume to justify the costs of continuing to develop the chips, Sadana said. He said the under-use of the factory is slated to cost Micron $400 million this year.
After exiting the 3D Xpoint market, Micron plans to shift its development efforts to take advantage of a new, faster industry standard for connecting memory chips to computing chips called Compute Express Link.
“We will have a (return) on this new investment that will be much higher because it will be easier for the software ecosystem to adopt,” Sadana said.
Micron jointly developed the 3D Xpoint memory with Intel starting in 2012. The company currently has a supply agreement with Intel that runs through the end of this year. Intel has said it plans to develop future generations of the chips, for which it uses a different brand name called “Optane,” at one of its factories in New Mexico.
Sadana said Micron will keep all the intellectual property associated with 3D Xpoint but is in contact with multiple potential buyers for the factory. While he could not name the parties or how much the factory might sell for, he said the bidders could go beyond memory companies to include makers of computing chips, analog chips or chip contract manufacturers.
