Kioxia pitches NAND flash as a partial DRAM substitute
The company says a CXL module is already with customers for evaluation, but Nikkei's paywalled report leaves the specifications unstated.

Kioxia's answer to AI memory demand is a CXL module built on faster NAND flash that is meant to take over part of DRAM's workload and is now under customer review.
At a glance
- Kioxia Holdings laid out the plan on Thursday: faster NAND flash taking over a share of DRAM's job.
- The product is a CXL module, described in the report as already undergoing customer reviews.
- Target buyers are large U.S. technology companies; the report casts Chinese memory makers as the rivals.
- Unverified: capacity, throughput, latency, pricing and production timing — the article is paywalled.
- Sourcing: one independent newsroom only (Nikkei Asia), as of September 4, 2026.
Kioxia's pitch for the AI memory market is a CXL module built around faster NAND flash, meant to absorb work that today sits in DRAM. Nikkei Asia reports the module is already with customers for evaluation. The intended buyers are large U.S. technology companies, and the report frames Chinese memory makers as the competition.
Cheaper capacity, slower parts
NAND costs far less per gigabyte than DRAM but responds far more slowly, which is why it has stayed on the storage side of the machine. Kioxia's argument is that a fast enough NAND tier can take over a slice of the memory workload rather than replace DRAM outright. That is a positioning claim. The visible part of the report does not quantify it.
What CXL buys a data center
CXL lets a processor reach memory that is not wired directly to its own controller. Operators can therefore add capacity as an attached device instead of filling every server with DRAM modules. Treat that as background on the standard, not as a statement from the company.
The unverified list
The Nikkei story is paywalled and only the opening paragraphs are public. Capacity per module, throughput, latency, pricing, sampling and mass-production dates, and the identities of the reviewing customers are all missing. This account also rests on a single independent newsroom, dated September 4, 2026. Until a second outlet confirms it, the plan is a company announcement rather than a tested product claim.
FAQ
What did Kioxia actually announce?
A CXL module using faster NAND flash to take over part of the workload normally handled by DRAM. The report says customers are already reviewing it.
Is CXL flash a replacement for DRAM?
Not a full one. The plan described is partial substitution: NAND is cheaper per gigabyte but slower, so only a share of the memory workload would move.
How fast is the Kioxia module and when does it ship?
Neither is public. The readable portion of the report gives no throughput, latency, capacity, price or shipping date.
