Kioxia announces its BiCs8 QLC NAND FLASH memory with the highest capacity on the market, reaching 2 TB

Kioxia continues with its roadmap and today they have announced its new QLC-type 3D NAND FLASH memories with a capacity of 2 Tb (TeraBits). They belong to the eighth generation of its BiCs Flash 3D memories and are capable of reaching 3.6 Gbps of bandwidth.

With this capacity per chip, the BiCS8 become the highest capacity memories in the industry. To achieve this, CBA (CMOS Directly Bonded to Array) technology has been integrated, which allows them to increasing chip density up to 2.3 times compared to the previous generation BiCs7. The jump is even greater, 70% more, when compared to the BiCs5.

We are talking about a small memory module measuring just 11 x 13.5 mm that can hold 16 of these chips to achieve a capacity of 4 TB with a height of just 1.5 mm. This opens a new door to the integration of greater storage capacities into mobile devices and all kinds, without requiring more space.

Alongside these 2TB BiCs8 chips, Kioxia has also launched a 1TB variant for solutions that do not require as much capacity, but are more sensitive to performance. In fact, these 1TB chips achieve 30% faster sequential write speeds and 15% lower read latency.
