The invention relates to a memory card with a serial advanced technology attachment (SATA) transmission interface, which comprises a connector of the SATA transmission interface, an internal storage module, a controller and a power supply control circuit, wherein the connector of the SATA transmission interface of the memory card is used for connecting the slot of an electronic device, wherein the connector comprises nine pins respectively used for receiving electric power, distinguishing the signal of the SATA interface, transmitting the signal of the SATA interface and grounding; the controller is electrically connected to the connector and the internal storage module so as to control the data transmission between the memory card and a computer; and the power supply control circuit is electrically connected to the connector, the internal storage module and the connector so as to supply the electric power required by the memory card.
Description
technical field [0001] The invention relates to a memory card, especially a memory card with a SATA transmission interface. Background technique [0002] With the development of information and the advancement of computer technology, the volume of computer systems is shrinking day by day, and the applications are becoming more diverse. In order to expand the functions of the computer system and adapt to the different needs of users, various external devices for the computer system have emerged as the times require. For example, external hard drives or portable storage devices, such as removable memory cards (SD, CF, MMC, MS, SDHC, M2, etc.), can expand the limited storage capacity of the computer system; external The optical drive and CD burner can expand the multimedia resource access function of the computer system and provide the ability of large-capacity data backup. At present, many removable memory cards with standard specifications have been developed, such as SD ca...
