Abstract
A memory card () is provided with data terminals (DATA/SDIO, DATA, DATA, DATA) for making two-way communication of 4-bit parallel data with a host apparatus on four data communication lines, a clock terminal (SCLK) for receiving a clock from the host apparatus, and a terminal (BS) for receiving, from the host apparatus, a bus-state signal indicating the states of the 4-bit parallel data communication lines and transfer start timing. The first data terminal (DATA/SDIO) is used as a data terminal for a memory card intended for 1-bit data communication to maintain the compatibility with this memory card.
