  • Patent number: 10277258
    Abstract: According to one embodiment, in a case where a first command is received from a host, a storage device starts a first process. The storage device transmits a first response to the host in a case where a first condition is satisfied and transmits a second response and an interrupt signal to the host in a case where the first process is completed. The host, in a case where the first response is received, stops the polling and receives the second response based on reception of the interrupt signal.

  • Publication number: 20180075902
    Abstract: According to one embodiment, a semiconductor storage device includes a first memory cell capable of storing n-bit data (n is a natural number not less than 4). When receiving first data, including first and second bits of the n-bit data, from a controller, the semiconductor storage device writes the received first data to the first memory cell. After receiving the first data, when the semiconductor storage device receives second data including third and fourth bits of the n-bit data, the semiconductor storage device reads the first and second bits from the first memory cell and writes the n-bit data to the first memory cell based on the read first and second bits and the received second data.
