A memory system includes a non-volatile memory and a controller that includes a first memory and is configured to write log data to the first memory, including a history of commands for controlling the memory system. An information processing system includes the memory system and an information processing device configured to store an expected value and to transmit a signal that instructs the memory system to stop when a value of the log data transmitted from the memory system does not match the expected value. The expected value and the transmitted value are determined based on the log data of the memory system.

Memory system and information processing system

A semiconductor device includes a transmission and reception circuit and a control circuit. The transmission and reception circuit transmits and receives a signal to and from a semiconductor memory device. The control circuit acquires threshold voltage distribution information of a memory element connected to a word line for read disturb detection to which a second voltage higher than a first voltage applied to an adjacent word line adjacent to a read target word line during a read operation is applied and determines an influence of read disturb based on the threshold voltage distribution information.

Semiconductor device, memory system and semiconductor memory device

A memory apparatus of an embodiment includes a nonvolatile semiconductor memory device, an error correction circuit, a memory circuit, a data distribution circuit, and a processing circuit. The error correction circuit performs error detection in data read from the nonvolatile semiconductor memory device on a processing unit size basis and performs error correction on the data in response to its necessity. The memory circuit stores data on the processing unit size basis. The data distribution circuit transfers the data read from the nonvolatile semiconductor memory device to the error detection circuit and the memory circuit on the processing unit size basis. The processing circuit reads the data from the memory circuit and processes the data in response to the error correction circuit detecting an uncorrectable error in the data.

Memory apparatus and data read method

An in-vehicle device performing communication with a mobile terminal device includes a vehicle exterior communication unit, an in-vehicle detection unit that detects a vehicle present location, a vehicle interior communication unit that acquires detection information on an object from a detection unit, and an in-vehicle control unit that generates recognition information including position information on the object based on vehicle position information indicating the vehicle present location and the detection information on the object and makes the vehicle exterior communication unit deliver the recognition information. The vehicle exterior communication unit receives existence notification information transmitted from the mobile terminal device when the mobile terminal device receiving the recognition information judges that the in-vehicle device has not recognized existence of a first object equipped with the mobile terminal device.

A pre-FEC packet quality analyzermeasures quality information from a video stream which is not yet stored in a bufferand on which a recovery process using FEC is not yet carried out. A post-FEC packet quality analyzermeasures quality information from the video stream which is stored in the bufferand on which the recovery process using FEC is carried out. A video receiving terminal profile transmittergenerates a video receiving terminal profile including at least information showing the size of the buffer, and transmits the video receiving terminal profile to a home gateway device.
