Kioxia develops the industry’s First 2 TB microSDXC Memory Card working prototypes

Kioxia Exceria Plus Prototype 2 TB

Kioxia Corporation, formerly known as Toshiba Memory Corporation, today announced the industry’s first two terabytes (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 over a decade. However, 2 TB cards have not been successfully manufactured until now.

The KIOXIA 2 TB card working prototypes are designed and built using the company’s proprietary manufacturing technology by stacking sixteen one terabit dies of 3D flash memory, achieving 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.
