If you’ve ever wondered what actually goes into the flash memory chips and SSDs that power the things you use every day (think laptops, mobile phones, data centers, automobiles, and countless connected devices), you’re not alone. Linus Tech Tips recently visited Kioxia Corporation’s Yokkaichi wafer fab in Japan and took viewers along for an exclusive behind-the-scenes tour - and this newly released video pulled in more than 1 million views within its first 24 hours.
In the video, Linus Sebastian gets an insider’s view of one of the world’s most advanced flash memory facilities, including Kioxia’s flagship Fab 7 (Y7). The tour shows how raw silicon becomes BiCS FLASH™ 3D flash memory, highlighting the engineering behind 32-die stacked memory chips, advanced automation, and the cleanroom precision required for reliable production at scale.
The video also follows those memory chips into SSD manufacturing, surface mounting components, heating/cooling PCBs, and final testing on a prototyping line - offering a rare look at the full journey from wafer to storage solution.
Curious about how the storage you rely on every day is actually made? Linus shows you here: https://www.youtube.com/watch?v=ivLvsTnp9fI
