Abstract
An embedded MultiMediaCard (eMMC), an electronic device equipped with an eMMC and an eMMC engineering board are disclosed. The eMMC includes an eMMC substrate plate, a plurality of solder balls and an eMMC chip. The solder balls are soldered to the eMMC substrate plate, and, one of the solder balls is designed as a security protection enable/disable solder ball. The eMMC chip is bound to the eMMC substrate plate, and, the eMMC chip has a security protection enable/disable pin electrically connected to the security protection enable/disable solder ball. The security protection enable/disable pin is internally pulled high by the eMMC chip when the security protection enable/disable solder ball is floating. When the security protection enable/disable solder ball is coupled to ground, the eMMC is protected from software-based attacks.
