Kioxia Europe Unveils Working Prototypes of 2TB microSDXC Memory Card
Using BiCS flash 3D flash memory and in-house controller
This is a Press Release edited by StorageNewsletter.com on October 6, 2022 at 2:02 pmKioxia Europe GmbH announced the development of the first [1] 2TB microSDXC memory card working prototypes.
Using its BiCS FLASH 3D flash memory and an in-house-designed controller, basic functions of the company’s 2TB microSDXC UHS-I memory card working prototypes were confirmed in the microSDXC standard’s maximum density.
As the data recording capacity of smartphones, action cameras and portable game consoles continues to increase, the need for high-capacity SD memory cards to store all this data has been higher. The SD Association’s SDXC spec has supported memory cards up to 2TB for more than a decade – but 2TB cards have not been successfully manufactured until now.
Designed using the company’s proprietary manufacturing technology, the 2TB card working prototypes are built by stacking 16x1Tb dies of 3D flash memory and achieve a maximum thickness of 0.8mm at the die-mounting area – making them suited to high-capacity data recording applications.
Mass production of the 2TB microSDXC memory cards is scheduled to begin in 2023.
