In a nutshell: Japanese memory manufacturer Kioxia recently announced the development of the first functional prototypes of 2 terabyte (TB) micro SDXC (Secure Digital eXtended Capacity) memory cards. Kioxia used its BiCS 3D flash memory and its own memory controller to showcase basic functionality at maximum standard density. In particular, Kioxia installed 16 single-terabit 3D flash memory chips with a total thickness of 0.8 mm.
How to data requirement record As smartphones, handheld game consoles and action cameras continue to grow, the need for ultra-high capacity storage is greater than ever. Cloud storage and streaming services help in certain cases, but for devices that generate data, local storage is still better.
The SD Association (SDA) SDXC specification has supported cards up to 2TB for over a decade, but so far no one has successfully produced them. SDA is a non-profit organization established in 2000 by SanDisk, Toshiba and Panasonic to set the world standard for memory cards. To date, the organization lists over 750 member companies on its website.
Kioxia is a relatively new name in the memory industry. Toshiba adopted this brand at the end of 2019. The name, pronounced kee-ox-ee-uh, is a combination of the Japanese word work kioku meaning “memory” and the Greek word axia meaning “value”.
Just a few days ago, Kioxia said it was fewer plate starts about 30 percent at the flash memory factories in Yokkaichi and Kitakami. The company said the move will help it better manage production and sales, and will continue to review and adjust operations as necessary.
Last month, analyst firm TrendForce said excess inventory was forcing manufacturers to cut prices on existing products. In the fourth quarter, we may see another 20% drop in NAND flash wafer prices, which is great news for those looking for cheap storage solutions. The market will eventually correct itself, but who knows when that might happen.
Mass production of 2TB Kioxia microSDXC memory cards is scheduled to begin sometime in 2023. No target pricing or more specific availability is known yet.
