- NAND of 332 layers of kioxia delivers 2TB without using tech plc
- The Japanese flash giant focuses on performance and capacity through the double axis development approach
- The suggestions are that you can deliver SSD even of greater capacity, as part of “Gen X”
Kioxia has revealed through the updated roadmap materials that its next 332 -layer NAND chip, part of its tenth gene generation flash, will offer 2 TB of dice.
While this may seem small compared to expectations, the Japanese flash specialist has insinuated that SSD of greater capacity can offer, as part of generation X, without resorting to the technology of Penta level cells (PLC).
The slides of the road map, published by TechpowerupThey were shared as part of Kioxia’s long -term corporate strategy.
Double axis strategy
The 332 -layer chip, which is currently under development, is part of what Kioxia calls its “double axis strategy” for Nand. This strategy divides development into two paths: the first focuses on increasing layer count for greater capacity and the second performance improving through position -based architecture (CBA).
CBA connects CMOS circuits directly to the memory matrix, helping to increase bandwidth, reduce latency and lower energy consumption.
Kioxia says that this approach allows you to increase density without sacrificing resistance and reliability associated with less bits per cell.
The Kioxia road map does not discuss the company’s plans for PLC, although other competitors are beginning to explore that address. Instead, Kioxia seems to be doubling the improvements in the process and the new controller designs to meet market demands.
The company’s recent approach has been in two SSD families: the CM9 series, which emphasizes high performance for AI applications, and the LC9 series, which is aimed at a large capacity and currently offers a capacity of up to 122 TB.
Both products are based on the BICS flash of the eighth generation of Kioxia, which introduced CBA and admits high -performance high -performance work loads in energy.
Kioxia also revealed a high IOPS SSD that has developed using its SLC XL-Flash technology. This SSD is expected to exceed 10 million IOP and the sample in the second half of 2026.
