A memory card for enhancing the reading performance is provided to automatically perform the change of address and command by an accelerator without the intervention of a program. A host interface controller(310) provides an interface related to a host(200) and includes a register set(311). Information such as an address, a command and the like provided from the host and the interrupt information are stored in the register set and initialized whenever the interrupt operation is finished. An MCU(Main Controller Unit)(320) controls the entire operation of a memory card. The MCU fetches an address and a command stored in the register set when the interrupt information is set to the register set.
