Provided is a memory card. The memory card includes interconnection terminals for electric connection with an external electronic machine. The interconnection terminals may be spaced from the front side of the memory card by a distance greater than the lengths of the interconnection terminals. Alternatively, the memory card may include other interconnection terminals between its front side and the former interconnection terminals. The former and latter interconnection terminals may be used for electric connection with different kinds of electronic machines.

Memory cards and electronic machines

Disclosed is a semiconductor memory device that includes a plurality of channel memories mounted within a package and is capable of minimizing or reducing the number of through-silicon vias. With the semiconductor memory device, a row command or a row address on two or more channels is applied through a shared bus. The semiconductor memory device is capable of reducing an overhead of a die size by reducing the number of through-silicon vias. A method of driving a multi-channel semiconductor memory device including a plurality of memories, using a shared bus, is also provided.

Multi channel semiconductor memory device and semiconductor device including the same

A memory module comprises a plurality of main memories; a buffer RAM configured to temporarily store data being provided to or read from the main memories and to perform a buffer function between an external device and the main memories; and a NAND flash memory configured to store data of the buffer RAM during an interruption of power being supplied to the buffer RAM.
