Kioxia in Mass Production of 2TB microSDXC UHS-I Exceria Plus Memory Card

Kioxia Europe GmbH started mass production of the 2TB microSDXC memory card for smartphone owners, content creators and on-the-go gamers.

With enhanced performance and capacity, the card is here to put less limits on what users can record and store ^[1].

By leveraging proprietary manufacturing technology including its BiCS 3D flash memory and an in-house designed controller, the company has successfully manufactured a 2TB microSDXC UHS-I memory card. Though the SD Association’s SDXC spec has supported memory cards up to 2TB for over a decade, the firm accomplished this challenge by stacking 16x1Tb dies of 3D flash memory while maintaining the spec’s maximum thickness of 0.8mm.

With read speed up to 100MB/s ^[2] and write speed up to 90MB/s ^[2], Exceria Plus G2 2TB microSDXC memory cards meet UHS Speed Class 3 (U3) ^[3], Application Class 1 (A1) ^[4] and Video Speed Class 30 (V30) ^[3].

The 2TB capacity allows users to record over 41 hours of video (100Mb) ^[5], making them suited for high-capacity data recording applications like action cameras.

“These new, enhanced cards can become a sought-after option by many smartphone owners, content creators, dashcam and video bloggers, and on-the-go gamers alike,” says Jamie Stitt, GM, B2C sales and marketing. “We are pleased to offer extra performance and capacity through these new Exceria Plus G2 2TB microSDXC cards.”

Market introduction of Exceria Plus G2 2TB microSDXC memory cards is scheduled to begin in the coming quarter.

^[2] 1MB/s is calculated as 1,000,000 bytes/s. These values are the best values obtained in a specific test environment at Kioxia Corporation and Kioxia Corporation warrant neither read nor write speeds in individual devices. RW speed may vary depending on a device used and file size read or written. The write speed is lower than the read speed. The data transfer speed in legacy SD interface is lower than the speed in UHS-I interface.
