Dubbed 'µcard', the format will support up to 2TB of storage capacity within a 3.2 x 2.4 x 0.1cm card - the same size as a standard MMC unit. The new cards are said to be connector-compatible with the older format.
The new cards will have a data transfer rate of 120MBps, ten times that of SD memory cards. Like the Secure Digital format, µcard will support I/O devices, such as Bluetooth and 802.11 adaptors.
