Nano Memory

From HandWiki
Short description: Memory card format created by Huawei
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 utilize the eMMC 4.5 protocol[4] and operate with read speeds of 90 MB/second.[2] Because of this, there are efforts to hook them into (Micro)SD interfaces with pure passive adapters in order to access them as true MMC cards[5], and such adapters are already available on Chinese market[6]. Some NM cards prove to even have boot blocks and RPMB, which are usually only present on non-removable eMMC chips.

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.[7] They are more expensive than SD cards.[8][9]
