A data prefetch apparatus provided between a main memory formed of a plurality of memory blocks and an I/O device whose data transfer speed is slower than that of the main memory, comprising an address counter for the main memory and a data buffer for storing the data prefetched from the main memory. In the data prefetch apparatus, a full/empty detector is connected to the data buffer and a memory block detector is connected to the address counter and the data prefetch is interrupted when the over-access of the one of the memory block is detected and is restarted when the data buffer is empty and data request is supplied from the I/O device.
