Abstract
A storage device may load, between a first time point at which information on candidate memory regions among a plurality of memory regions is started to be sent to an external device and a second time point at which a command requesting a map segment for a target memory region among the plurality of memory regions is received from the external device, all or a part of map segments corresponding to the candidate memory regions into a buffer.
Claims15
A storage device comprising:
- a memory including a plurality of memory regions;
- and
- a controller configured to send information on one or more candidate memory regions selected from among the plurality of memory regions to an external device, and to load all or a part of map segments corresponding to the candidate memory regions into a buffer between a first time point when the information on the candidate memory regions begins to be sent to the external device and a second time point when a command requesting a map segment for a target memory region, from among the plurality of memory regions, is received from the external device.
A method for operating a storage device, comprising:
- beginning to send information on candidate memory regions from among a plurality of memory regions to an external device at a first time point;
- loading all or a part of map segments corresponding to the candidate memory regions into a buffer after the first time point;
- receiving a command requesting a map segment for a target memory region from among the plurality of memory regions at a second time point;
- and
- sending the map segment for the target memory region to the external device.
2 more elements
A controller comprising:
- a memory interface capable of communicating with a memory including a plurality of memory regions;
- a host interface capable of communicating with a host;
- and
- a control circuit configured to, after a host performance booster (HPB) recommend command indicating information on candidate memory regions among the plurality of memory regions is sent to the host and before an HPB read buffer command requesting a map segment for a target memory region among the plurality of memory regions is received from the host, load in advance all or a part of map segments corresponding to the candidate memory regions into a buffer.
