Kioxia Develops Industry’s First 2TB microSDXC Memory Card Working Prototypes

Kioxia Corporation, a world leader in memory solutions, today announced the industry’s first 2 terabyte (TB) microSDXC memory card working prototypes. Using its innovative BiCS FLASH 3D flash memory and an in-house designed controller, basic functions of the KIOXIA 2 TB 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 ultra-high capacity SD memory cards to store all of this data has never been higher. The SD Association’s SDXC specification has supported memory cards up to 2 TB for more than a decade—but 2 TB cards have not been successfully manufactured until now.

Designed using the company’s proprietary manufacturing technology, the KIOXIA 2 TB card working prototypes are built by stacking sixteen 1 terabit dies of 3D flash memory and achieve a maximum thickness of 0.8 mm at the die mounting area – making them well-suited to high-capacity data recording applications.

Mass production of the KIOXIA 2 TB microSDXC memory cards is scheduled to begin in 2023.
