Nano Memory

From Wikipedia, the free encyclopedia
NM card

Nano Memory (NM) is a proprietary memory card format developed by Huawei in 2018.[1]

NM cards are the same size as a nano SIM card, so they can be used in the same slots as nano SIMs.[2] They are smaller than micro SD cards, freeing up space and reducing weight in smartphone designs.[3]

NM cards utilise the eMMC 4.5 protocol[4] and operate with read speeds of 90MB/second.[2]

As of 2021, the cards were only supported by Huawei phones, however they are also manufactured by Lexar. Available sizes are 64GB, 128GB, and 256GB. They are more expensive than SD cards.[5][6]
