The present technology relates to an electronic device. According to the present technology, a memory controller may include a garbage collection controller and a sustain detector. The garbage collection controller may generate garbage collection information including valid page count values of victim memory blocks on which garbage collection is to be performed among a plurality of memory blocks included in a memory device. The sustain detector in communication with the garbage collection controller may generate sustain information indicating whether random write performance for the memory device is in a sustain state in which a random write performance value related to a capability of the random write performance is greater than or equal to a threshold value based on the garbage collection information.

Memory controller for controlling communication with host and method of operating the same

A memory system includes a memory device including a plurality of planes each including a plurality of memory blocks; and a memory controller for controlling the memory device to perform an operation on target blocks among the plurality of memory blocks, to store, in a replacement block, data stored in a bad block, on which the operation fails among the target blocks, and control the memory device to temporarily store, in a backup block, data stored in the other blocks except the bad block among the target blocks according to a number of free blocks included in the memory device.

Memory system and operating method for multi-plane program thereof

A memory system includes a memory device including plural memory blocks and a controller configured to perform garbage collection on a victim block among the plural memory blocks. The controller is further configured to stop the garbage collection in response to an interrupt and invalidate a valid data item, which is copied from the victim block to a target block during the garbage collection.

Apparatus and method for securing a free memory block in a memory system

Memory controller devices, memory systems, and operating methods for memory controller devices and memory systems are disclosed. In one aspect, a memory controller having improved wear leveling performance is disclosed. The memory controller may control a first memory area and a second memory area, and include a first software layer configured to control the first memory area based on first logical addresses, a second software layer configured to control the second memory area based on second logical addresses, and a logical address manager configured to compare a logical address received from a host with a reference address selected from among a plurality of logical addresses to be used by the host, and transmit the logical address received from the host to the first software layer or the second software layer according to a criterion selected from between a first criterion and a second criterion based on the comparison.

Memory controller and method of operating the same

A memory controller includes a first flash translation layer (FTL) generating a physical address corresponding to a first type logical address received from a host on the basis of information about the first memory blocks, a second FTL generating a physical address corresponding to a second type logical address received from the host on the basis of information about the second memory blocks, and a memory control unit controlling the first memory area or the second memory area to perform an operation on the physical address corresponding to the first type logical address or the physical address corresponding to the second type logical address, wherein the first FTL provides the second FTL with block request information for requesting use of the second memory blocks, and generates the physical address corresponding to the first type logical address received from the host on the basis of block allocation information provided by the second FTL.

Memory controller for replacing bad blocks with reserved blocks and operating method thereof
