Patent ID: 8910310

Claim:
An embedded flash memory card, comprising: an embedded flash memory card substrate plate and a plurality of solder balls, wherein the solder balls are soldered to the embedded flash memory card substrate plate, and, one of the solder balls is designed as a security protection enable and disable solder ball; and an embedded flash memory card chip bound to the embedded flash memory card substrate plate, wherein the embedded flash memory card chip has a security protection enable and disable pin electrically connected to the security protection enable and disable solder ball and the security protection enable and disable pin is internally pulled high by the embedded flash memory card chip when the security protection enable and disable solder ball is floating, wherein: the security protection enable and disable solder ball is floating when the embedded flash memory card is mounted on an embedded flash memory card engineering board; the security protection enable and disable solder ball is soldered to a ground line of a printed circuit board of an electronic device when the embedded flash memory card is mounted in the electronic device; the embedded flash memory card chip further comprises a controller and, when the security protection enable and disable solder ball is coupled to ground, the controller disables a plurality of vendor commands to protect the embedded flash memory card from software-based attacks; and the controller enables the plurality of vendor commands when the security protection enable and disable pin is pulled high.
