Kioxia and Sandisk Introduce Advanced 3D Flash Memory with 4.8Gb/s Speed

A New Era in Flash Memory

Get ready to geek out, because Kioxia Corporation and SanDisk Corporation are shaking things up in the world of flash memory. At the recent ISSCC 2025 conference, these two tech giants launched their latest innovation: a 3D flash memory technology that’s not just fast—it’s blazing fast. With a jaw-dropping 4.8 Gb/s NAND interface speed, this new tech is setting a high bar for the industry, and trust us, it’s not just about speed.

What Makes It Tick?

So, what’s the secret sauce behind this revolutionary technology? It’s all about the combination of their advanced CBA (CMOS directly Bonded to Array) technology and the latest interface standard, Toggle DDR6.0. This duo is a game-changer, especially with the introduction of the SCA (Separate Command Address) protocol, which redefines how command addresses are handled. Plus, the innovative PI-LTT (Power Isolated Low-Tapped Termination) technology plays a crucial role in minimizing power consumption.

But hang on—there’s more! This new 3D flash memory is not just faster; it also boasts a significant 33 percent improvement in NAND interface speed compared to the 8th generation. And if you think that’s impressive, consider this: it achieves enhanced power efficiency, cutting down power consumption by 10 percent for inputs and a staggering 34 percent for outputs. It’s all about striking that perfect balance between high performance and low power usage.

A Peek Into the Future

Looking ahead, Kioxia and Sandisk are already teasing their 10th generation 3D flash memory. How do they plan to up the ante? By cranking up the number of memory layers to an astonishing 332 and optimizing the floor plan for greater density. This means a whopping 59 percent improvement in bit density. Can you imagine the possibilities?

Hideshi Miyajima, Kioxia’s Chief Technology Officer, put it perfectly: “With the proliferation of AI technologies, the amount of data generated is projected to increase significantly, and so is the need for increased power efficiency in the modern data center.” He believes this new technology will pave the way for larger capacity, higher speed, and lower power consumption products—think SSDs that can keep up with our ever-growing digital demands.

Catering to Diverse Needs

Alper Ilkbahar, the SVP of Global Strategy and Technology at Sandisk, echoed this sentiment, highlighting the shifting landscape of customer needs as AI technology advances. “Through our CBA technology innovation, we aim to launch products that deliver the best mix in terms of capacity, speed, performance, and capital efficiency to cater to our customers across market segments.” In other words, they’re not just building tech for tech’s sake; they’re crafting solutions tailored to real-world demands.

The Road Ahead

But wait, there’s still more on the horizon! Kioxia and Sandisk are also gearing up for their 9th generation 3D flash memory. Thanks to their unique CBA technology, they’re combining new CMOS tech with existing memory cell technology to create products that are not only high-performance but also capital-efficient and low-power.

Both companies are committed to pushing the envelope in flash memory technologies, ensuring they’re not just meeting customer needs but anticipating them. As we continue to navigate this digital age, innovations like these will play a crucial role in shaping our future. So, buckle up—this is just the beginning of an exciting journey into the world of memory technology!
