1. Introduction to the SD Card 
The SD Card is a memory card that is small and thin with SDMI. SD Card is a Flash–Based memory card that is 
designed to meet the security, capacity, performance and environment requirements inherent to used in emerging 
audio and video electronic device. 
The SD Card includes a copyright protection mechanism that complies with the security of the SDMI standard (SDMI: 
Secure Digital Music Initiative). 
The SD Card communication is based on an advance 9-pin interface (clock, command, 4x Data and 3x power lines) 
and the SD Card host interface supports regular MultiMediaCard operation as well.
