  • Publication number: 20200243140
    Abstract: A storage device includes a nonvolatile memory device and a controller. The controller provides the nonvolatile memory device with first data, an address, and a program start command and provides the nonvolatile memory device with second data after the program start command is provided the nonvolatile memory device. The nonvolatile memory device is configured to initiate a program operation, which is based on the first data, in response to the program start command and to continue to perform, based on the first data and the second data, the program operation when the second data is provided to the nonvolatile memory device. The nonvolatile memory device is configured to perform a program and a verification read of a first program loop based on the first data, the verification read of the first program loop being performed using one verification voltage.

  • Patent number: 9594389
    Abstract: Provided are a device and a method for automatically coordinating a protection device of a smart power distribution management system, wherein a protection coordination correction value of the protection device is calculated via topology analysis and system analysis of a distribution system so as to apply the result to a smart power distribution management system. The device for automatically coordinating a protection device as provided comprises: generating the topology information by obtaining the status information of the distribution system; setting machines, which transmit and received data when an event occurs, to communicate for each of a plurality of protection devices based on the topology information; calculating a system power flow including the power flow direction based on the topology information; and calculating a fault current which is generated upon the failure of the distribution system based on the topology information, thereby generating a protection coordination correction value.
