20130232296 | MEMORY SYSTEM AND CONTROL METHOD OF MEMORY SYSTEM - A memory system in embodiments includes a nonvolatile semiconductor memory that stores user data, a forward lookup address translation table and a reverse lookup address translation table, and a controller. The controller is configured to determine that the user data stored in the nonvolatile semiconductor memory is valid or invalid based on these two tables. The controller may perform data organizing of selecting data determined valid and rewriting the data in a new block. The controller may perform write processing and rewriting processing to the new block alternately at a predetermined ratio. The controller may determine whether a predetermined condition is satisfied on a basis of addresses included in write requests and write data in the MLC mode when the condition is satisfied and write data in the SLC mode when the condition is not satisfied. | 09-05-2013 |

20130238837 | STORAGE DEVICE WHICH CAN PERFORM STABLE COMMUNICATION BETWEEN HOST AND STORAGE DEVICE, AND METHOD OF CONTROLLING THE SAME - According to one embodiment, a storage device includes a nonvolatile memory, an interface, a register, and a controller. The nonvolatile memory stores communication speed information. The interface communicates with a host. The register is included in the interface. The controller controls the nonvolatile memory and the interface. The controller reads the speed information from the nonvolatile memory and sets the speed information in the register when the device is started, and the interface communicates with the host based on the speed information set in the register. | 09-12-2013 |

20110310954 | PULSE WIDTH MODULATION COMMUNICATION SYSTEM - In a PWM communication system, a sensor unit transmits as reference pulses transmission signals, which exhibit duty cycles of 100% and 0%, respectively, prior to transmission of a transmission signal, which has data items compressed thereinto by a signal processing circuit. An input capture circuit of an ECU measures the duty time and the PWM cycle of the transmission signal according to a timer clock of a timer circuit. A signal processing circuit of the ECU produces a duty cycle correction factor k based on the measured duty times and PWM cycles of the reference pulses, produces receiving data based on the duty time and the PWM cycle of the transmission signal, and the duty cycle correction factor, and separates the receiving data into sensor output values of a pressure sensor and a temperature sensor. | 12-22-2011 |
