A storage device may generate mapping information between a plurality of memory regions and one or more namespaces. The storage device may record information on empty memory regions among the plurality of memory regions in an empty table, and may determine empty memory regions to be mapped to a target namespace among the empty memory regions recorded in the empty table.

Storage device translating logical address on the basis of sequentiality of namespace, and method thereof

Storage devices, methods of operating storage devices, and computing systems including storage devices are disclosed. In an embodiment, a storage device may include a plurality of memory devices and a memory controller for controlling the plurality of memory devices to process a request of a host in accessing plurality of memory devices, wherein the memory controller is configured to allocate the plurality of memory devices to a plurality of functions, allocate a plurality of request slots allowed to process the request per unit time for each of the plurality of functions, determine idle request slots other than active request slots being used to process the request among the plurality of request slots allocated to each of the plurality of functions, and control an internal operation of the plurality of memory devices based on at least one target function including the idle request slots among the plurality of functions.

Storage device, method of operating the same, and computing system including the storage device

A controller includes at least one register configured to store a doorbell regarding a submission queue storing at least one request generated by a host, a first cache configured to store data corresponding to a first result of an operation performed in response to the at least one request, a second cache configured to store data corresponding to a second result of an operation performed in response to a read look ahead (RLA) request generated based on the at least one request, and a cache size manager configured to adjust a size of the second cache based on an update cycle of the doorbell and a change of a number of the at least one request corresponding to the doorbell.

Apparatus and method for adjusting cache allocated for read look ahead

A storage device, a controller, and a method for performing global wear-leveling may count write counts of a plurality of respective cores in each of a plurality of logical areas each including logical block address groups of the plurality of cores, determine, on the basis of degradation counts of the plurality of cores, a first core and a second core for which data swap is to be performed, determine a target logical area among the plurality of logical areas on the basis of a write count of the first core and a write count of the second core, and perform data swap between a first logical block address group of the first core included in the target logical area and a second logical block address group of the second core included in the target logical area.

Storage device, controller and method for performing global wear-leveling

The storage device may receive a condition for a down-time mode from the host. The storage device may cache, when the condition for the down-time mode is determined as satisfied, at least a part of update data units in the update cache. The storage device may process a read command received from the host in the down-time mode based on update data units cached in the update cache.
