A memory system may include a storage device, a buffer memory and a memory controller. The buffer memory may include a first portion and a second portion. The memory controller may detect a set event, store external data in the first portion before the event is detected, and store the external data in the second portion after the event is detected. The external data is associated with a read request or a write request from an external device.

Memory system adaptively allocating a buffer memory, memory controller and method of operating the same

A memory system and an operating method thereof are provided. The memory system includes a buffer memory storing a plurality of meta-slices constituting meta-data, and a memory controller marking meta-slices being updated, among the plurality of meta-slices stored in the buffer memory, as dirty meta-slices, generating journal data including update information corresponding to the dirty meta-slices, and flushing the journal data together with one of the dirty meta-slices to a non-volatile memory device.

Memory system and operating method thereof

A method for operating a data storage device includes determining an ngarbage collection throughput by multiplying a rate of a number of used pages of an open memory block to an amount of write data to be processed to a sum of the number of used empty memory blocks and an immediately previous garbage collection throughput average value; and performing a garbage collection operation based on the ngarbage collection throughput.
