According to ServeTheHome, Kioxia has shown the XL1, a second-generation XL-FLASH NAND device that attaches to a system as a 512GB memory expansion over a CXL interface. The demonstration positions the device as a way to extend memory capacity using flash rather than conventional DRAM.
The XL1 is described as XL-FLASH Generation 2, indicating a newer iteration of Kioxia's specialized NAND for this role. Because it is presented as a memory expansion device, the emphasis is on using the flash to add system memory, not as ordinary storage.
The report notes the device was shown, but it does not include performance figures, pricing, or a release timeline. Until more specifications are published, the practical impact of the XL1 remains unclear.
