STORAGE DEVICE CONFIGURED TO MANAGE PLURAL DATA STREAMS BASED ON DATA AMOUNT

摘要

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.

1. A storage device comprising:
one or more nonvolatile memories; and a memory controller configured to control the one or more nonvolatile memories such that write data of each of a plurality of data streams is stored in the one or more nonvolatile memories, each of the data streams being associated with a corresponding requested stream identifier from among a first number of requested stream identifiers provided from a host, wherein the memory controller comprises:
a write amount manager configured to manage information associated with a data amount of each of the data streams associated with the corresponding requested stream identifiers;a stream manager configured to map the first number of the requested stream identifiers to a second number of processing stream identifiers, based on the information associated with the data amount, such that the data streams are provided to the one or more nonvolatile memories according to the second number of the processing stream identifiers; anda mapping manager configured to manage information associated with mapping between the first number of the requested stream identifiers and the second number of the processing stream identifiers.
