  • Patent number: 8031537
    Abstract: In the storage device of the invention, latch control is performed on a series of signals in response to latch control signals. Latch control terminals are provided to which the latch control signals are input respectively and a plurality of signal terminals to which a series of signals are input. Herein, a plurality of latch circuits is provided so as to correspond to the plurality of signal terminals, respectively. The plurality of latch circuits are located within a specified distance from their associated signal terminals respectively and within a specified distance from the latch control terminals. The delays of signal transmission from the signal terminals to their associated latch circuits can be equalized and the delays of signal transmission from the latch control terminals to which the latch control signals for executing latch control are input to the latch circuits can be equalized. This contributes to a reduction in the skew of the latch characteristics of the signals.

  • Patent number: 7739559
    Abstract: A semiconductor device (1) is provided which includes a regular cell array unit (30), a redundant cell array unit (31) that is provided in relation to the regular cell array unit (30), and a PGM/ER state machine (20) that controls reprogramming in which, when programming of a sector in the regular cell array unit fails (step S3), data involved in the programming that fails and data already stored in the sector in the regular cell array unit are written (step S8) into the redundant cell array unit (31). Since reprogramming is performed to write the data already written in the sector as well as the data involved in the programming that fails into the redundant cell array unit (31), data loss can be prevented and data can be secured, thereby increasing the reliability of the system.

  • Patent number: 6658517
    Abstract: A communication controlling apparatus, which is connected to a telephone line and a serial bus, comprises a mapping table, which brings a fixed address, which a terminal device possesses, into correspondence with a node ID assigned to a terminal device connected to the current serial bus. Then, the node ID of the terminal device, serving as a recipient of data received from the telephone line, is obtained from the mapping table, and the received data from the line is transmitted to the terminal device via the serial bus using the obtained node ID.

  • Patent number: 5499213
    Abstract: A semiconductor memory device has an oscillator unit for generating refresh pulses, a refresh address detection unit for detecting refreshed addresses and outputting a predetermined signal upon the completion of the refreshing of all addresses, and an output control unit for continuing a self-refresh mode to refresh all addresses according to the signal from the refresh address detection unit, before releasing the self-refresh mode in response to an external signal. Therefore, the refresh operation is continued until all cells are refreshed, thereby data stored in the semiconductor memory device is not lost and is correctly refreshed.
