The latest trend of a smartphone that can be seen in 2 minutes.Dramatically speed up by evolution of memory

Smartphone is a digital gadget that emphasizes speed.Although PCs and tablets are also focused on speed, it is a smartphone that the most advanced technology is first introduced today, so if you look at the latest models of each company, you can see the advanced technology that leads to speeding up.One of them is "flash memory".Speaking of flash memory, we imagine a detachable SD / microSD card and SSD, but EMMC, which is not for built -in / detachable in digital gadgets, is the mainstream.However, EMMC is the past in the most advanced smartphone, and as of 2021, it is being replaced by alternative technologies such as "UFS (UNIVERSAL FLASH STORAGE)".There are several versions of UFS specifications, as of 2021, the flagship machine of the Android device is "UFS 3."1" is often adopted.Conventional UFS 2.New functions such as "WriteBoost", which increase the writing speed by 2-3 times compared to 1, and "UFS -DEEP SLEEP POWER MODE", which reduces power consumption, achieves a higher -speed and energy -saving internal storage.

UFS 3.1に対応したUFSモジュール「iNAND MC EU521」UFS 3.1における理論上の最高速度は23.2 Gビット/秒。eMMC 4.5（最大1.6Gビット/秒）やeMMC 5.0（最大3.2Gビット/秒）と比べると圧倒的な圧倒的に高速です。これほどの高速性があれば、8K映像など転送速度が求められるコンテンツの記録にも余裕で対応できそうです。なお、フラッシュメモリの接続規格としては、iPhoneやPS5の増設用スロット（エムドットツー）などに採用されている「NVMe」もあります。こちらも実効速度で31.5Gビット/秒という速さですから、ストレージの高速性が求められるデジタルガジェットで見かける機会は増えるかもしれません。
