So far, most of the CXL devices we have seen are Type-3 memory expansion devices, but Kioxia demonstrated a CXL + BiCS flash memory-based product.
Note: CXL is a technology jointly developed by Intel, AMD and other companies, which supports memory sharing and cache sharing, and can be used in cloud computing, artificial intelligence, high-performance computing and other fields.
As shown in the figure, Kioxia has two different CXL series products, one is CXL + BiCS traditional flash memory, and the other is CXL + XL-Flash (Kioxia’s SLC NAND SLC solution).
In fact, it’s interesting to see if the specs of this series of flash memory, and this will be one of the first CXL x4 products. According to reports, it can be read using CXL.mem and written using CXL.io.
In August last year, Kioxia launched its second-generation XL-FLASH product, which is a storage (SCM) solution based on BiCS FLASH 3D flash memory technology, which can greatly reduce unit cost while providing high performance and low cost. Delay.
According to reports, in addition to the SLC unit of the existing model, the second-generation XL-FLASH has added an MLC part per unit, which greatly reduces the cost, but its capacity is only 256 GB.
