  • MEMORY CARD SUPPORTING NEAR FIELD COMMUNICATION THROUGH SINGLE WIRE PROTOCOL
    Publication number: 20130062417
    Abstract: A memory card supporting near field communication through single wire protocol includes a power management unit, an interface control unit, a data storage unit, a power protection unit and an intelligent unit. The power protection unit is interposed between the power management unit and a near field voltage source of the near field communication unit to prevent short-circuit induced by direct connection there between. Moreover, direct connection between the power management unit and the intelligent unit can also be prevented, which can protect against bursts of excessive voltages or currents that may damage the data in the intelligent unit. Additionally, the power protection unit can prevent power leakage from the power management unit and the near field voltage source, which solves the problem of improperly driving near field communication or insufficient power supply to the interface control unit or intelligent unit.
