Abstract
In an embodiment of the disclosed technology, a storage device starts in advance loading map data before outputting a signal corresponding to a read buffer command of a host device, encodes map data using a plurality of map load areas and a plurality of encoding areas, and provides encoded map data to the host device.
Claims20
A storage device comprising:
- a memory including a plurality of storage areas;
- and
- a controller configured to transmit, to a host device, a read buffer recommend signal on the basis of a read count for data stored in each of the plurality of storage areas, and start a load operation of storing, in a buffer memory, map data associated with the read buffer recommend signal before receiving, from the host device, a read buffer command corresponding to the read buffer recommend signal.
A controller comprising:
- a buffer memory;
- a first processor configured to output a read buffer hint signal when a read count is greater than or equal to a preset value, the read count for data stored in each of a plurality of storage areas included in an external memory, and start a load operation of storing map data associated with the read buffer hint signal in the buffer memory;
- and
- a second processor configured to transmit, to a host device, a read buffer recommend signal in response to the read buffer hint signal, the read buffer recommend signal being transmitted after the load operation is started.

A controller comprising:
- a buffer memory;
- a first processor configured to output a read buffer hint signal when a read count is greater than or equal to a preset value, the read count for data stored in each of a plurality of storage areas included in an external memory, and store, in a map load area of the buffer memory, map data associated with the read buffer hint signal;
- and
- a second processor configured to transmit, to a host device, a read buffer recommend signal in response to the read buffer hint signal,
- wherein the second processor transmits, to the host device, a first read buffer recommend signal and a second read buffer recommend signal, encodes first map data stored in a first map load area of the buffer memory and stores the encoded first map data in a first encoding area of the buffer memory in response to a first read buffer command corresponding to the first read buffer recommend signal, and encodes second map data stored in a second map load area of the buffer memory and stores the encoded second map data in a second encoding area of the buffer memory in response to a second read buffer command corresponding to the second read buffer recommend signal.
