Moore’s law states that the processor productivity is doubled every 18 months. Later, this law was spread to other semiconductors but … memory. Currently, at least two smartphone components are exceptions rather than regularity. They are the batteries and memories. However, the companies are working hard to bring larger-capacity batteries and memories that will also support faster charging and faster read/write speed. In this regard, we should inform you that Kioxia officially announced that its Tokyo branch had launched the industry’s first prototype of a 2TB microSDXC memory card. The latter is scheduled to start mass production in 2023.

The memory card adopts BiCS FLASH 3D flash memory and self-developed main control. It is composed of 16 3D flash memory chips with a capacity of 1Tb stacked. The maximum thickness of the chip installation area is 0.8 mm, which is suitable for large-capacity data recording applications.
As the data of smartphones, action cameras, and portable game consoles continues to increase, the demand for SD memory cards with large capacities is becoming more and more obvious. Although the SDXC specification has always supported 2TB, no company has successfully manufactured such a large memory card.
Also, we have to mention that the 2TB memory card of Kioxia is quite friendly to Nintendo players because the Switch supports up to 2TB SDXC memory card. However, after the Kioxia 2TB microSDXC memory card is mass-produced and listed in the market, we should also meet the new generation of Switch.
By the way, Kioxia is the new identity of Toshiba Memory after its name change. It is still one of the world’s largest NAND flash memory chip manufacturers. So that’s not surprising that the world’s first 2TB SD memory card comes our way from this firm. But we also think that other rivals will begin producing similar products after its mass production.
