Abstract: A storage device includes: a nonvolatile memory including power loss protector (PLP) memory blocks configured to store at least one of meta data or user data for data backup; a buffer memory configured to store at least one of the meta data or the user data stored in the PLP memory blocks; a charging circuit configured to generate electric power for data backup in response to a sudden power off (SPO) occurrence, and transmit a first charging complete signal or a second charging complete signal to a processor according to a level of the electric power, and; and the processor configured to control at least one of the nonvolatile memory and the buffer memory to execute a first request from a host related to the meta data with priority in response to the first charging complete signal, and execute a second request from the host related to the meta data or the user data in response to the second charging complete signal.

Abstract: A storage device includes one or more nonvolatile memories, and a memory controller that controls the nonvolatile memories such that write data of data streams is stored in the nonvolatile memories. The data streams have a first number of requested stream identifiers provided from a host. The memory controller includes a write amount manager that manages information about a data amount of each of the data streams having the requested stream identifiers, a stream manager that maps the first number of the requested stream identifiers with a second number of processing stream identifiers, depending on the information associated with the data amount, such that the data streams are provided to the nonvolatile memories according to the second number of processing stream identifiers, and a mapping manager that manages information about mapping between the first number of the requested stream identifiers and the second number of the processing stream identifiers.
