  • Patent number: 12381030
    Abstract: A coil component includes a core that has a columnar winding core portion and a flange formed at an end of the winding core portion in an axial direction. The coil component also includes a terminal electrode formed at an end surface of the flange and a wire being wound around the winding core portion with one end portion coupled to the terminal electrode. The flange protrudes toward the first end of the coil component in the first direction. A curved surface and an inclined surface are formed at a boundary between a surface of the flange and a peripheral surface of the winding core portion. The inclined surface has a curvature smaller than that of the curved surface. In addition, the inclined surface is disposed where the wire intersects the boundary as viewed in the first direction.

  • Patent number: 11362830
    Abstract: A memory system is communicable with a plurality of hosts. The memory system includes a nonvolatile memory and a controller electrically connected to the nonvolatile memory. The controller receives an authentication request command from a first host, and transmits a first authentication code when authentication of the first host is successful. The controller receives an access command, which includes a second authentication code, for accessing the nonvolatile memory from a second host. The controller permits an access to the nonvolatile memory in accordance with the access command when the second authentication code matches the first authentication code, and prohibits an access to the nonvolatile memory in accordance with the access command when the second authentication code is different from the first authentication code.
