Maximum capacity of SD card is 4GB under v.1.1 spec. and is also 4GB for MMC under v.4.1 spec. using so called "Byte Addressing" scheme if the file format of FAT32 is adopted. Pretec 4GB MMC Plus can be configured to be fully compliant with MMC 4.1 specification under traditional "Byte Addressing"; or alternatively Pretec 4GB MMC Plus can be configured under "Sector Addressing" scheme pioneered last year by Mu-Card Alliance in which Pretec is a founding and major contribution member. Maximum capacity of Mu-Card is 2TB (2048GB), which can potentially soon become the maximum capacity of future specification of MMC card.
