Tokyo's Tech Marvel: Kioxia's 2Tb QLC Memory Chips



Hey tech enthusiasts! Have you heard the latest buzz from Tokyo? Kioxia Corporation, a global leader in memory solutions, has just dropped a bombshell. They’ve started sample shipments of their 2Tb (terabit) Quad-Level-Cell (QLC) memory devices, powered by their cutting-edge eighth-generation BiCS FLASH™ 3D flash memory technology. This isn't just another tech update; it’s a game-changer!

Why is this news so epic? Well, this 2Tb QLC device boasts the highest capacity in the industry, taking storage devices to an entirely new level. Imagine the possibilities! From AI to data centers, this innovation will drive growth across multiple application segments. Now, let’s dive deeper and see what makes this memory chip so special.



First things first, let’s talk about what’s under the hood. Kioxia’s new memory devices feature their latest BiCS FLASH™ technology. This isn’t your run-of-the-mill tech; we’re talking about both vertical and lateral scaling of memory die through proprietary processes and innovative architectures. Say what? In simpler terms, they’ve managed to pack more memory into a smaller space more efficiently than ever before.

But wait, there’s more! The company has also implemented CBA (CMOS directly Bonded to Array) technology. This groundbreaking tech enables the creation of higher-density devices and an industry-leading interface speed of 3.6Gbps. Together, these advanced technologies culminate in the creation of the 2Tb QLC, making it the highest capacity memory device in the industry. Talk about pushing the envelope!



Okay, so Kioxia’s 2Tb QLC memory devices are super advanced, but what does that mean for us mere mortals? Well, for starters, this chip has a bit density approximately 2.3 times higher and a write power efficiency about 70% higher than Kioxia’s current fifth-generation QLC device. This is huge!

Imagine a 16-die stacked architecture in a single memory package. The latest QLC device achieves an industry-leading 4TB (terabyte) of capacity, all in a smaller package size of 11.5 x 13.5mm and a package height of just 1.5mm. This isn’t just a leap in technology; it’s a quantum leap. Whether you’re into AI, big data, or just need more storage for your cat videos, this device has you covered.



Don’t just take my word for it. Listen to what the big shots are saying. Charles Giancarlo, CEO of Pure Storage, Inc., couldn’t be more thrilled. He says, “We have a long-standing relationship with Kioxia and are delighted to incorporate their eighth-generation BiCS FLASH™ 2Tb QLC flash memory products to enhance the performance and efficiency of our all-flash storage solutions.”

Pure Storage aims to meet the demanding needs of artificial intelligence and the aggressive costs of backup storage. Backed by Kioxia technology, they promise unmatched performance, power efficiency, and reliability. Sounds like a win-win for everyone!

And let's not forget Hideshi Miyajima, Kioxia's Chief Technology Officer. He’s equally pumped, saying, “With its industry-leading high bit density, high-speed data transfer, and superior power efficiency, the 2Tb QLC product will offer new value for rapidly emerging AI applications and large storage applications demanding power and space savings.” When tech leaders are this excited, you know something big is happening.


If you thought Kioxia was stopping at 2Tb, think again. They’ve also introduced a 1Tb QLC memory device to their portfolio. While the 2Tb QLC is optimized for capacity, the 1Tb QLC focuses on performance. It offers approximately 30% faster sequential write performance and around 15% improvement in read latency compared to its larger sibling.

The 1Tb QLC is perfect for high-performance applications, including client SSDs and mobile devices. So whether you need massive storage for your data center or blazing-fast performance for your personal gadgets, Kioxia has got you covered.



So, what’s next for Kioxia? The company is committed to developing industry-leading memory products to meet the growing demand for data storage solutions. With innovations like the 2Tb and 1Tb QLC memory devices, they’re not just keeping up with the times; they’re setting the pace.

In a world where data is the new oil, Kioxia’s advancements are like discovering a new energy source. So keep your eyes peeled and your devices ready because the future of memory technology is here, and it’s brighter than ever!

So there you have it, folks! Kioxia's latest innovations are set to revolutionize the tech world. From AI to personal storage, these new memory devices are paving the way for a more efficient, powerful, and exciting future. Stay tuned for more updates, and until next time, keep dreaming big and storing bigger!
