    摘要: A host device and a slave device are set to a full-duplex mode by temporarily switching the communication direction of a first transmission channel or a second transmission channel after completing transmission and reception of a predetermined number of data packets in the half-duplex mode. The host device or the slave device can thus transmit an interrupt request, such as a request associated with a wait status or a busy status, to its communication target using the temporary full-duplex mode. This enables the host device or the slave device to process such an interrupt request during high-speed data transfer performed in the half-duplex mode.

    摘要: A data communication system for starting transmission and reception of target data for processing upon recognition that switching between communication modes is completed. The data communication system includes a master communication device and a slave communication device that continuously perform, at a time of switching from half-duplex communication to full-duplex communication, (i) a handshake using a directional control code indicating the switching and a preamble code indicating completion of the switching and (ii) a handshake using the preamble code and an acknowledge code indicating receipt of the preamble code, whereby each of the devices recognizes that the switching between communication modes by the opposite device is completed and starts transmission and reception of the target data.

    摘要: An interrupt request cannot be transmitted while a data read command or a data write command transmitted from a host device to a slave device is being processed in a half-duplex mode. Disclosed are a host device and a slave device that are set to a full-duplex mode by temporarily switching the communication direction of a first transmission channel or a second transmission channel after completing transmission and reception of a predetermined number of data packets in the half-duplex mode. The host device or the slave device can thus transmit an interrupt request, such as a request associated with a wait status or a busy status, to its communication target using the temporary full-duplex mode. This enables the host device or the slave device to process such an interrupt request during high-speed data transfer performed in the half-duplex mode.

    摘要: In a memory system including a host device and one or more nonvolatile memory devices, the host device reads, from a nonvolatile memory device connected in the system, a boot code used to operate a CPU of the host device before the CPU is activated. The boot code reading process is required to be performed with a simple method. A host device (2) transmits a first symbol including a synchronous code to a nonvolatile memory device (1). The nonvolatile memory device (1) receives the first symbol from the host device (2), and transmits a first symbol that is identical to the received first symbol to the host device (2), and then transmits a boot code to the host device (2). In this manner, the host device (2) reads a boot code from the nonvolatile memory device 1 with a simple method.

    摘要: In a communication system in which data is transmitted and received in synchronization with a clock signal, a peripheral device cannot transfer data to a host device when the host device stops outputting the clock signal and thus the peripheral device cannot promptly transmit an interrupt request to the host device. A peripheral device transmits an interrupt request to a host device using a signal line for a clock signal when the clock signal output has been stopped. The host device receives the interrupt request, and resumes outputting a clock signal to enable data transmission and reception to and from the peripheral device. This enables the peripheral device to transmit an interrupt request to the host device promptly when the output of the clock signal from the host device has been stopped.

    摘要: It has been difficult for an access device to obtain a remaining capacity of a memory from a nonvolatile memory device having a plurality of interfaces. A capacity parameter generation part 127 and a capacitor parameter notification part 128 are provided in a memory controller 120. When data is written or deleted, the capacity parameter generation part 127 generates a capacity parameter based on a physical region management table 125. The capacity parameter notification part 128 sends the generated capacity parameter to an access device 200. The access device 200 obtains a remaining capacity of the nonvolatile memory device 100 from the received capacity parameter.
