What is a Nano Memory Card?

The Nano memory card (NM) is a proprietary format developed by Huawei in 2018 called nCard. Nano-memory cards are the next big thing in memory storage. They’re the same size as nano SIM cards so you can use them on your phone just like a nano SIM card. They’re smaller than micro SD cards, so you’ll save space and weight when designing smartphones.

Nano memory cards run on eMMC 4.5 protocol and have read speeds of 90MB/second. They’re only supported by Huawei phones as of 2021, but we’ve also seen them manufactured by Lexar. Available sizes are 64GB and 128GB, with 256GB coming soon!

How is a Nano Memory card different from a microSD card?

You’ve probably heard about Nano memory—but do you know what it is and how it’s different from microSD cards?

Nano memory is a new type of storage that’s smaller than a regular memory card but bigger than a flash drive. It’s super small, so you can carry more of it around in your pocket or purse without worrying about being bulky. The main advantage of Nano memory is that it can hold more data than standard memory cards.

It’s also way faster than regular memory cards, which might make your phone run faster because the processor doesn’t have to wait as long for data to be retrieved from the card when you open an app or load a website.
