<p>A control section (7) controls a nonvolatile memory (2). A plurality of data terminals (DAT0 to DAT3), and a command terminal (CMD) are connected to a host (10), and transfer and receive data and a command to and from the host. A buffer memory temporarily stores the data. The control section (7) outputs a filled state of the buffer memory to a first data terminal of the plural data terminals as a write busy signal indicating a write busy period by a block write command operation in which the number of blocks to be transferred is defined, receives a token issued by the block write command, and outputs the write busy signal indicating the write busy period to the first data terminal until an end of the token processing.</p> |
