Micro SD is the smallest flash memory which is so small that it is the size of a thumbnail. In comparison to standard SD cards, these micro SD cards are only one eighth in size, and today, even devices that are meant to used standard SD cards are fitted with adaptors to use these small memory cards. However, it is not possible to use these micro SD cards in all devices which is why manufacturers are today supplying these cards with adaptors to make it easy for the user to fit these cards in their devices.
Micro SD format is developed by a company called San Disk. While Micro SD cards provide an external memory of 1-2 GB, new cards have been developed with capacity to hold more data. These are called Micro SD HC cards and can amazingly hold 4-32 GB of data. Micro SD HC cards provide removable memory for many digital devices such as cameras, camcorders, MP3 players etc.
