  • Patent number: 10580513
    Abstract: An address generation circuit generates a target address to be tested in a memory. A test data generation circuit generates write data for the address and expected value data for read data from the address. A judgment circuit compares matching/non-matching of the read data and the expected value data, for each address, judges that error correction is possible when the number of non-matching bits is within a range of numbers of bits to be error-corrected by an ECC circuit, and judges that error correction is not possible when the number is not within the range.

  • Patent number: 10553811
    Abstract: A method of manufacturing an organic electroluminescence display panel includes forming pixel electrode layers in a matrix on a substrate. The method includes arranging column banks extending in a column direction above the substrate. The method includes applying ink containing organic light emitting material to gaps between the column banks so that the ink is continuous between ends of the column banks in the column direction. The method includes arranging the substrate and a rectifying plate facing each other, the rectifying plate having a uniform density of through holes, such that the rectifying plate is at a predefined distance from the column banks. The method includes exhausting gas from an environment including the substrate and the rectifying plate. The method further includes heating the substrate to dry the ink to form an organic functional layer. The method includes forming a counter electrode layer above the organic functional layer.

  • Publication number: 20190386989
    Abstract: A first controller generates a first group key, executes first mutual authentication with devices within a group, and shares the first group key with the devices that have succeeded in first mutual authentication. When a second controller joins the group, the first controller decides a coordinator that manages a group key used in common in the group. The first controller executes second mutual authentication with the coordinator, and shares the first group key with the coordinator when the second mutual authentication is successful. The coordinator performs encrypted communication within the group using the first group key, generates a second group key when valid time of the first group key is equal to or smaller than a predetermined value, executes third mutual authentication with the devices and a third controller, and updates the first group key of the devices and the third controller that have succeeded in the third authentication.

  • Patent number: 10504609
    Abstract: There is to provide a semiconductor device capable of realizing a start time diagnosis on a non-volatile memory without any external device and any non-volatile memory out of a diagnosis target. The non-volatile memory includes an address space formed by addresses continuously read and a reservation address formed by a single or a plurality of addresses, read after the address space. A previously calculated value fixed data is stored in the reservation address. When all the data stored in the address space and the value fixed data are compressed using a predetermined initial value according to a predetermined compression algorithm, the value fixed data is the data for converging the compression value to a predetermined fixed value (for example, 0).

  • Patent number: 10440021
    Abstract: A first controller generates a first group key, executes first mutual authentication with devices within a group, and shares a first group key with devices that have succeeded in authentication. At least one controller within the group decides a coordinator that manages a group key used in common in the group, from controllers including a second controller newly joined in the group. The first controller executes second mutual authentication with the coordinator, and shares the first group key with the coordinator. The coordinator performs encrypted communication within the group using the first group key. The coordinator generates a second group key when valid time of the first group key is equal to or smaller than a predetermined value, executes third mutual authentication with the devices and controllers within the group, and updates the group key of the devices and controllers that have succeeded in authentication to the second group key.
