Memory card of handheld equipment and dynamic mounting method of memory card

The invention discloses a memory card of handheld equipment. Based on an Android system, the memory card comprises an internally-arranged memory card; the internally-arranged memory card is divided into a first storage region and a second storage region; the first storage region is an ROM (Read Only Memory); a system program and/or an application program of the handheld equipment are/is stored in the ROM; and the second storage region belongs to a user storage space, is mainly used for storing relative data for a user and can also be used for mounting the application program. A dynamic mounting method of the memory card is used for dynamically selecting mounting between the second storage region of the internally-arranged memory card and an externally-inserted T card. According to the memory card of handheld equipment, the mounting path of the second storage region of the internally-arranged memory card and the externally-inserted T card is replaced, so that the utilization efficiency of a cell phone is improved and the cost is saved.
