20 Claims

1. A nano memory card comprising:

a card body comprising:

a first surface; and

a second surface opposite from the first surface;

a chip disposed inside the card body; and

an interface disposed on the first surface and electrically coupled to the chip, wherein the interface comprises:

first surface contacts distributed on the first surface and configured to transmit data, wherein the first surface contacts comprise a first contact group and a second contact group that are disposed at intervals along a first direction, wherein the first contact group comprises a first contact, a second contact, a third contact, and a fourth contact that are disposed in sequence along a second direction, wherein the second contact group comprises a fifth contact, a sixth contact, a seventh contact, and an eighth contact that are disposed in sequence along the second direction, wherein the first direction is different from the second direction, wherein the first contact, the third contact, the fifth contact, and the eighth contact are configured to transmit the data, wherein the second contact is configured to transmit a power supply signal, wherein the fourth contact is configured to transmit a clock signal, wherein the sixth contact is configured to transmit a first power supply ground signal, and wherein the seventh contact is configured to transmit a command signal; and

second surface contacts distributed on the second surface and configured to transmit the data,

wherein the second surface contacts comprise a third contact group and a fourth contact group that are disposed at intervals along the first direction,

wherein the third contact group comprises a ninth contact and a tenth contact that are disposed in sequence along the second direction,

wherein the fourth contact group comprises an eleventh contact and a twelfth contact that are disposed in sequence along the second direction, and

wherein the ninth contact, the tenth contact, the eleventh contact, and the twelfth contact are configured to transmit the data.
