Abstract: An electronic apparatus includes: a converter including a switching device, an inductor, and an output capacitor; a protection switching device provided between the inductor and the output capacitor; and a protection circuit configured to provide a control voltage to: turn on the protection switching device based on a first voltage applied between the inductor and the protection switching device, the first voltage being lower than or equal to a threshold level corresponding overvoltage, and turn off the protection switching device based on the first voltage, the first voltage being higher than the threshold level. The control voltage is varied depending on variation in the input voltage or the output voltage and having a level corresponding to a threshold voltage for turning on or off the protection switching device.

Abstract: A storage device includes nonvolatile memory devices arranged in groups, and a controller connected with the groups respectively through channels. The controller is configured to generate an access request for a nonvolatile memory device among the nonvolatile memory devices, and transmit, based on the access request, access requests respectively to two or more groups, among the groups, respectively through two or more channels, among the channels.

Abstract: A storage device includes a controller and a nonvolatile memory device. The controller includes a field programmable gate array (FPGA) and receives an FPGA image for updating the FPGA from an outside in response to a first command received from the outside. The nonvolatile memory device stores the FPGA image. The controller receives the FPGA image through a main interface or a sideband interface, and executes the FPGA image in response to a second command received from the outside.
