  • Patent number: 7941730
    Abstract: A semiconductor memory has a field programmable unit in which logic to inter-convert external signals to be input/output to/from a memory system and internal signals to be input/output to/from a memory cell array is programmed. A program for constructing the logic of the field programmable unit is stored in a nonvolatile program memory unit. Through the field programmable unit, a controller can access the memory cell array, even when the interface of the controller accessing the semiconductor memory is different from an interface for accessing the memory cell array. Therefore, one kind of semiconductor memory can be used as plural kinds of semiconductor memories. This eliminates the need to develop plural kinds of semiconductor memories, reducing a development cost.

  • Patent number: 7937645
    Abstract: A conversion control unit sets a converting function of a write data conversion unit or a read data conversion unit enabled or disabled for each controller. Accordingly, for a controller which needs original external data, the external data can be inputted and outputted, whereas for a controller which needs converted internal data, the internal data can be inputted and outputted. A data converting function of a conventional controller can be realized in a semiconductor memory, which can reduce the load on the controller. As a result, the performance of a system can be improved. A disabled controller which has no access right cannot read correct data (original data before conversion). Hence, the security of data written into the semiconductor memory can be protected.

  • Patent number: 7827468
    Abstract: A volatile memory has a volatile additional area for storing an error correction code for a nonvolatile memory. Data stored in the nonvolatile memory are transferred to the volatile memory together with the error correction code without making an error correction. Thus, data transfer time from the nonvolatile memory to the volatile memory can be shortened. As a result, it is possible to shorten the time from beginning of the data transfer from the nonvolatile memory to the volatile memory to a point at which data becomes accessible.

  • Patent number: 7661079
    Abstract: A method of designing a semiconductor integrated circuit includes defining a tolerable range in which an operating temperature and an operating power supply voltage of a semiconductor integrated circuit are allowed to vary, computing a target temperature and a target power supply voltage that cancel variation in circuit characteristics caused by process variation of the semiconductor integrated circuit, separately for each circuit characteristic responsive to the process variation, and designing the semiconductor integrated circuit such that the semiconductor integrated circuit properly operates with any temperature and power supply voltage within the tolerable range based on an assumption that the semiconductor integrated circuit is to operate within the tolerable range centered substantially at the target temperature and target power supply voltage.

  • Patent number: 7561455
    Abstract: A controller converts a parallel command signal and address signal, or a parallel write data signal into a first serial signal, and outputs the converted signal as a first optical signal with a single wavelength to a memory device via an optical transmission line. The memory device converts the first optical signal into the original parallel command signal, address signal, and write data signal, and outputs the converted parallel signals to a memory unit. The memory device converts a parallel read data signal from the memory unit into a second serial signal, and outputs the converted signal to the controller via the optical transmission line as a second optical signal with a single wavelength. It is unnecessary to transmit the optical signal using an optical multiplexer, an optical demultiplexer, etc., thereby improving transmission rate of signals transmitted between the controller and the memory device at minimum cost.

  • Patent number: 7417884
    Abstract: A memory controller multiplexes access signals each consisting of a plurality of bits as optical signals and outputs the multiplexed optical signals. At this time, the optical signals whose wavelengths differ depending on memory devices are generated. A memory interface unit demultiplexes the multiplexed optical signals into the original optical signals and converts the demultiplexed optical signals into electrical signals. The memory interface unit determines to which of the memory devices the electrical signals resulting from the conversion should be outputted, according to the wavelengths of the demultiplexed optical signals. This frees the memory controller from a need for transmitting to the memory interface unit a signal for identifying the memory device. The memory interface unit need not include a decoding circuit for identifying the memory device.

  • Patent number: 7388791
    Abstract: Plural transmitter units generate plural currents corresponding to plural logical values, respectively, and propagate the currents to a common signal line. The common signal line synthesizes the currents generated by the transmitter units, and propagates them to a receiver unit as a synthetic current. The receiver unit restores the logical values the transmitter units generated, in accordance with the synthetic current. The values of the currents the transmitter units generate in correspondence with the logical values each differ, so that the value of the synthetic current can be changed for every combination of logical values. Accordingly, the receiver unit can restore the logical values outputted from the respective transmitter units, based on the synthetic current. That is, employing the common signal line enables signals transmitted from the transmitter units to be simultaneously received. Consequently, the number of signal lines laid between the transmitter units and the receiver unit is reduced.
