Nano Memory

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 utilize the eMMC 4.5 protocol^[4] and operate with read speeds of 90 MB/second.^[2]

As of 2021, the cards were only supported by Huawei phones, however they are also manufactured by Lexar. Available sizes are 64 GB, 128 GB, 256 GB, and 512 GB.^[5] They are more expensive than SD cards.^[6][7]
