When it is determined that a first super memory block among a plurality of super memory blocks satisfies an exchange condition, the storage device may exchange a first memory unit in the first super memory block with a second memory unit included in a second super memory block among the plurality of super memory blocks. In this case, the first memory unit is a bad memory unit and the second memory unit is a normal memory unit.

Storage device distributing bad memory units in super memory block and operating method of the storage device

A storage device may group a plurality of memory dies into M memory die groups, and migrate, when a first memory die in a first memory die group among the M memory die groups is determined to be in an unusable state, user data stored in user data blocks of the first memory die to a first overprovisioning block group. The first overprovisioning block group may include overprovisioning blocks of memory dies other than the first memory die among the memory dies in the first memory die group.

Storage device migrating user data stored in memory die in an unusable state

A data storage device includes a storage and a memory controller. The storage is configured to store data. The memory controller generates meta-data including a mapping relationship between a logical address used in an external device and a physical address used in the storage. The memory controller generates a normal meta-slice having a first size including the meta-data in a first operation mode. The memory controller stores a meta-page including the normal meta-slice in the storage. The memory controller generates a modified meta-slice having a second size as a part of the normal meta-slice in the second operation mode. The memory controller stores a meta-page including the modified meta-slice and context data corresponding to size information of the modified meta-slice in the storage. The memory controller restores the meta-data based on the context data in a power-on mode.

Data storage device, memory controller and method of operating the same

Provided herein may be a memory controller and a method of operating the same. The memory controller may include a plurality of control cores configured to control a plurality of memory devices, respectively, a host core configured to allocate write requests received from a host to each of the plurality of control cores based on predefined criteria, and a shared memory configured to be accessed by the host core and the plurality of control cores, wherein, in response to occurrence of a sudden power-off, the host core is further configured to store, in the shared memory, dump information including information about logical addresses corresponding to the write requests, and wherein a first control core is further configured to store, in a memory device controlled by the first control core, the dump information of a second control core associated with the first control core.

Memory controller and method of operating the same

There are provided a storage device and an operating method thereof. The storage device includes: a memory device including a plurality of memory blocks, a buffer memory configured to temporarily store data, and a memory controller configured to, in response to occurrence of a power loss, generate address information including logical addresses of write data that correspond to the data temporarily stored in the buffer memory and meta data, and control the memory device to store the address information and the write data in a predetermined backup block group included in the plurality of memory blocks.

Storage device for storing address information and data in memory device in response to occurrence of power loss and operating method of the storage device

A memory system may write, when operating in a force unit access mode, first write data requested by the host to a buffer for temporarily storing data to be written the memory device and a first memory block among the plurality of memory blocks, and may write, when the size of the data accumulatively stored in the buffer is greater than or equal to A which is a unit of a size in which data is written to a second memory block among the plurality of memory blocks, second write data of size A among the data stored in the buffer to the second memory block. The operation speed of the first memory block may be set faster than the operation speed of the second memory block and the storage capacity of the first memory block may be set smaller than the storage capacity of the second memory block.

Memory system and operating method thereof

The disclosure provides novel chemical compounds represented by Formula I or a pharmaceutically acceptable salt, solvate, polymorph, ester, tautomer or prodrug thereof. The compounds can be used as an inhibitor of Trk and are useful in the treatment of pain, cancer, inflammation, neurodegenerative disease and certain infectious diseases.  In some compounds of Formula I, Q is &#x2014;CH&#x2550;CRC(O)NRR, &#x2014;C&#x2261;CC(O)NRR, or 

Fused ring heteroaryl compounds and their use as Trk inhibitors
