Abstract: A method for establishing an interface between a host and a plurality of memory devices of a system that utilizes a Multimedia Card (MMC) or Digital (SD) protocol according to an interleaving scheme. A host sequentially transmits a first sequence of commands and data to a system bus in order to allow a first memory device among the memory devices to perform a first operation. The host then transmits a second sequence of commands and data to the system bus to allow a second memory device among the memory devices to perform a second operation after transmitting the first sequence of commands and data.

Abstract: A method for establishing an interface between a host and a plurality of memory devices of a system that utilizes a Multimedia Card (MMC)/Secure Digital (SD) protocol according to an interleaving scheme. A host sequentially transmits a first sequence of commands and data to a system bus in order to allow a first memory device among the memory devices to perform a first operation. The host then transmits a second sequence of commands and data to the system bus to allow a second memory device among the memory devices to perform a second operation after transmitting the first sequence of commands and data.

Abstract: A debugging method employed by a memory card includes performing an initialization operation of the memory card, determining whether an error has occurred in the initialization operation, and upon the occurrence of an error during the initialization operation, executing an error control program when a first control command is input. The execution of the error control program performing an interrupt service routine, and jumping to a system initialization routine after the interrupt service routine is performed.
