Vertical and Lateral Scaling: A Powerful Combination

BiCS Powerful Combo of Vertical and Lateral Scaling

I recently chatted with EE Times for an interview on the latest trends in NAND Flash memory. In this discussion, I touched on what leadership in the era of 3D flash memory looks like – and the role that layer counts play in determining this.

Because the only constant is change, and this certainly applies to the ongoing conversation surrounding 3D flash memory, I speak often with customers, analysts and industry insiders to give an updated view on this topic.

At KIOXIA, we believe that technology leadership is determined not by how high you go, but by bringing the most cost-effective solution that meets the performance and density requirements, regardless of number of layers.

Last year we introduced the 8th generation of our BiCS FLASH™ 3D flash memory which brought an entirely new architecture designed to meet the needs of a diverse range of applications.

In a nutshell, our latest generation of BiCS FLASH 3D flash memory is all about combining vertical and lateral scaling. This powerful combination produces greater capacity with fewer layers - resulting in higher density, smaller die size and optimized costs1.

KIOXIA is committed to technological leadership, and to offering innovations that go beyond the race for the highest number of layers.

In every mention of a KIOXIA product: Product density is identified based on the density of memory chip(s) within the Product, not the amount of memory capacity available for data storage by the end user. Consumer-usable capacity will be less due to overhead data areas, formatting, bad blocks, and other constraints, and may also vary based on the host device and application. For details, please refer to applicable product specifications. The definition of 1KB = 2^10 bytes = 1,024 bytes. The definition of 1Gb = 2^30 bits = 1,073,741,824 bits. The definition of 1GB = 2^30 bytes = 1,073,741,824 bytes. 1Tb = 2^40 bits = 1,099,511,627,776 bits.
