Kioxia and Sandisk Debut 10th‑Gen QLC 3D Flash, Boosting AI and Cloud Storage Efficiency

10th-generation QLC 3D flash memory represents a major leap forward for AI storage architectures, cloud platforms, and data intensive innovations

Future of Memory and Storage Conference (FMS) – Kioxia Corporation, a subsidiary of Kioxia Holdings Corporation (TOKYO: 285A) and Sandisk Corporation (Nasdaq: SNDK) today unveiled their next-generation Quad-Level-Cell (QLC) 3D flash memory technology, which delivers up to 60% increase in bit density compared to their 8th-generation, surpassing 37 Gb/mm2 and setting the industry benchmark for bit density, performance and power efficiency.

Leveraging the companies’ revolutionary CMOS directly Bonded to Array (CBA) technology which fabricates CMOS logic and the memory array on separate wafers before bonding them together with high-precision wafer-to-wafer alignment, the new generation improves read and write bandwidth compared to the 8th-generation 3D flash memory and becomes the industry’s first QLC 3D flash memory technology to reach a 4.8 Gb/s 3 interface.

Additional interface enhancements improve I/O data-out transfer power efficiency. These large power efficiency upgrades directly address the power and cooling challenges of modern AI and cloud infrastructure.

Chief Technology Officer at Kioxia, Hideshi Miyajima, said: “As AI continues to underpin the advancement of society, its applications are expanding from generative AI to agent-based and physical AI, while the use of data is becoming increasingly diverse and sophisticated. QLC technology enables the efficient storage of rapidly expanding data volumes, helping deliver greater performance and scalability for AI systems. Kioxia will accelerate development toward the commercialization of its 10th-generation flash memory products incorporating QLC technology.”

Chief Technology Officer at Sandisk, Alper Ilkbahar, said: "As AI training, inference, and hyperscale datacenter workloads drive unprecedented growth in data generation, the storage industry faces increasing pressure to deliver greater capacity, higher performance, and improved energy efficiency. By redefining the performance and efficiency envelope of QLC NAND, our 10th-generation QLC 3D flash memory delivers simultaneous gains in density, bandwidth, and energy efficiency and establishes a new paradigm for high-capacity flash storage to provide a scalable foundation for next-generation infrastructure applications.”

Key 10th-generation QLC 3D flash memory technology highlights include:

• 332-layer architecture and optimized floorplan design deliver up to 60% increase in bit density, achieving >37 Gb/mm² compared to the 8th-generation.
• 4.8 Gb/s 3 NAND interface enabled by Toggle DDR6.0 and the Separate Command Address (SCA) protocol to unlock the full potential of fast interface.
• CMOS-directly-Bonded-to-Array (CBA) architecture enhances density scaling, performance, and manufacturing efficiency.
• Power-Isolated Low-Tapped Termination (PI-LTT) improves I/O data-out transfer power efficiency.

Sandisk and SK hynix Drive AI Infrastructure Standardization with High Bandwidth Flash Specification

Sandisk Corporation (Nasdaq: SNDK) and SK hynix Inc. today announced the release of the HBFTM (High Bandwidth Flash) technical specification through the Open Compute Project (OCP), advancing the workstream to drive HBF standardization for the AI inference era, just six months after the consortium began work in February.

The specification was developed through the HBF technology workstream under OCP, with Sandisk and SK hynix serving as primary contributors. Notably, Google and Tenstorrent joined as consortium members during this standardization process, contributing significantly to technology validation and the establishment of the standard. The specification provides companies and developers designing AI inference systems and accelerators with a common technical framework for incorporating HBF technology where larger, near-compute memory capacity and higher bandwidth are needed to improve power and performance metrics and help reduce total cost of ownership.

Modern AI inference systems need high-bandwidth memory positioned close to compute cores, while the demand for greater near-compute memory capacity continues to grow with the requirements of large language models and emerging AI workloads. HBF technology is designed to address this need by combining high bandwidth with high capacity, helping data center system designers improve interactivity and throughput during model serving.

“AI inference is creating a new set of memory requirements, and HBF technology is designed to meet that moment,” said Alper Ilkbahar, Chief Technology Officer, Sandisk. “This specification helps give system designers a practical path to bring high-capacity, high-bandwidth memory closer to compute, while enabling more flexible architectures. It is an important milestone for the HBF ecosystem and for the next generation of AI systems built to improve token economics at scale.”

The specification defines system interface, electrical and other technical guidelines for designing systems that interact with and use HBF technology, including basic performance expectations, the xPU-HBF host interface, reliability and packaging guidance for an HBF die stack, and a software user guide for read and write operations. As one of the first technical standards of its kind in the memory and storage industry, the specification helps give AI compute system designers added flexibility to build systems where HBF technology can coexist with High Bandwidth Memory, helping support ecosystem readiness. The specification was released within the Open Compute Project framework, meaning the information is openly available to the industry. Sandisk and SK hynix proactively published the specification to position HBF technology as the de facto standard in the rapidly evolving AI storage market. Their strategy involves fostering an early-stage ecosystem, increasing the visibility of HBF technology’s adoption for customers, and accelerating market expansion and technological maturity through open collaboration and membership in the consortium.

Sandisk Launched highest capacity SD card of 128GB in India

SanDisk has just released the world's first ever 128GB microSD card and of highest capacity till date, in India. The capacity of this SD card is more than any smartphone's internal memory.

A 32 GB Sandisk micro SD card is available on Flipkart at price of Rs.1399 however, this micro SD card of 128 GB will be available in India for price tag of Rs.9,999 which is almost whooping 10K.

It has a read speed of 30MB/s and is water-proof, temperature-proof, magnet-proof and shockproof. It also comes with an adaptor to full-sized SD if you want to switch it between your phone and a laptop or digital camera.

As the capacity of this card is larger than the smartphone itself, the only smartphones available in market that have this capacity of memory are only few such as - iPhone 5S, HTC One M8 and Samsung S5. Apart from memory capacity the Sandisk 128 GB micro SD card is also double in speed in comparison to other micro SD cards.

The card supports SDXC, which means that it should be compatible with most modern phones with microSD slots but unfortunately for many, one of major drawback of this SD card is - even if your phone allows for microSD card slots, not every phone support the massive 128GB of storage on the tiny compact card. You have to probably own iPhone 5S, HTC One M8 or Samsung S5 smartphones only otherwise you may end up wasting you almost Rs.10K of money.

Although Sandisk has already launched this 128 GB Sd card earlier in Mobile World Congress, in Barcelona, in february this year however the company has decided to launch it in India now.

To produce this 128GB microSD card, SanDisk developed a proprietary technique to stack 16 memory dies vertically, each is shaved to be thinner than a strand of hair, before being stacked.
