Kioxia develops microSD card with 2 TB memory

Memory specialist Kioxia has managed another innovation. The manufacturer, formerly known as Toshiba Memory, announced the developers of a microSDXC memory card with a capacity of two terabytes. They have even developed a working prototype.

Kioxia with 2 TB microSDXC memory card

Until now, the maximum capacity for microSDXC memory cards was 1 TB. Now, storage specialist Kioxia doubles the maximum data volume and launches a first prototype with 2 TB. About a year ago, the company launched the eponymous EXCERIA PLUS Portable SSD series, also with 2 TB storage capacity.

This is made possible by a new, innovative flash memory called BiCS-FLASH-3D. The controller for this comes from the company itself. The UHS-I memory card fulfills all SDXC specifications imposed by the SD Association. This is despite the fact that a correspondingly high capacity has already been officially supported for around ten years – only real 2 TB solutions have not yet been available.

Here, 16 dies of one terabit each are stacked on top of each other. However, it is unclear whether it is a QLC or TLC NAND. According to the manufacturer, the speed is up to 104 MB/s thanks to the UHS-1 standard. Thus, the new Kioxia microSDXC memory card is rather not designed for use in the absolute high-end segment.

Kioxia has already produced a first working prototype. However, the memory card is not expected to go into mass production until 2023 at the earliest and thus ultimately reach the market.

The manufacturer has not yet named prices. The microSDXC memory card Kioxia EXCERIA Plus with a capacity of 1 TB is currently offered in stores from around 240 Euros, but the 2 TB model is likely to be even more expensive.
