A non-volatile memory device includes a non-volatile memory array having a plurality of pages. Each page includes a plurality of non-volatile memory cells, a first region for storing data, and a second region for storing control data that is associated with the data of the first region. The non-volatile memory device further includes a read out unit for reading out data from the pages, and a data buffer for temporarily storing data that has been read out from the pages by the read out unit. When reading out the control data, the read out unit reads out the second regions, across a plurality of pages, at one time.

    摘要: The nonvolatile memory device prevents data writing from temporarily slowing down significantly in the middle of writing data to a block when an access device writes all the data in the block in units of a smaller size than the block. The nonvolatile memory device comprises a memory controller including an interface unit configured to receive a first command that identifies a first write range for writing data, and a second command that identifies a second write range that is a part of the first write range and orders to write data to the second write range, an address management unit configured to determine, before data is written into a nonvolatile memory, a new block for writing data to the first write range based on the first command, and a read/write control unit configured to write data to the new block in response to the second command.

    摘要: A nonvolatile storage device includes a controller and a nonvolatile memory. The controller has: a logical-physical address conversion part for converting a logical address designated by a host device into a physical address; and a boot code address conversion part for converting boot code address information designated by the host device into a physical address. After the power-on and before the logical-physical address conversion part becomes usable, a boot code is read from a part of region which can be accessed by designating a logical address from the host device by designating the boot code address information from the outside. Thus, it is possible to rapidly start the nonvolatile memory system after the power-on. In the state where the logical-physical address conversion part can be used, data-reading and data-writing are carried out by designating a logical address from the host device.

    摘要: A communication system including a master device and one or more slave devices enables parameters of the slave devices to be set in an efficient manner. A master device (2) transmits a parameter setting command as a broadcast command. A slave device (1) receives the parameter setting command, and compares the received parameter value with a parameter value stored in a parameter display unit, and transmits a parameter setting command to which the comparison result has been added. The master device (2) receives the parameter setting command transmitted from the slave device (1) and determines that the parameter setting has been completed.

    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.

The two driver circuits are connected to a power supply potential via the drive control circuit. Two input signals and inverted logic signals of the input signals are inputted via a selection circuit. According to a control signal inputted into the drive control circuit, the interface circuit switches between the voltage-driving type single-ended transmission system and current driving type differential transmission system.

    摘要: A host device transmits a command from a command transmission unit (101a) along a predetermined command sequence. A storage device (2) receives the command in a command reception unit (202a). An access determination unit (202c) determines the sequence of the command transmitted from the host device (1) and determines that reception of the access to the host device (1) is enabled only when the sequence is identical with a predetermined sequence. Thus, with simple control, it is possible to prevent data destruction by a host device of an old version.
