Abstract: In a method of operating a storage device, the storage device includes a plurality of memory blocks. A data write request and target data to be written are received. Using a data classifier, such as a neural network model, the target data is assigned to a stream selected from a plurality of streams based on a data property of the target data. The target data is written into a memory block assigned to a stream selected for assignment of the target data, such that target data that has been assigned to a stream are written into the one or more memory blocks assigned to the stream.

Abstract: Garbage collection is performed according to an estimated number of valid pages. A storage device estimates a valid page count at a future time based on a valid page count at each of past time steps and a present time step using a neural network model and selects a victim block that undergoes the garbage collection from memory blocks based on an estimated valid page count. A memory block having a lowest estimated valid page count or having an estimated valid page count having a maintaining tendency is selected as the victim block or a memory block having the estimated valid page count having a decreasing tendency is excluded from selecting the victim block.
