Abstract
A system for cache synchronization includes a data managing unit and a storage medium. The data managing unit is configured to control storing of data of a buffer cache of the storage medium, in response to an event signal received from a host, by classifying the data of the buffer cache into random data and sequential data. The storage medium includes a first area and a second area, and is configured to store the random data and an address information map in the first area, and to store the sequential data in the second area.
Claims17
A system for cache synchronization comprising:
- a data managing unit configured to control storing of data of a buffer cache of a storage medium, in response to an event signal received from a host, by classifying the data of the buffer cache into random data and sequential data;
- and
- the storage medium comprising a first area and a second area, the storage medium configured to store the random data and an address information map in the first area, and to store the sequential data in the second area.
A system for cache synchronization comprising:
- a data managing unit providing a journaling function for storing log information and storing data of a buffer cache of a storage medium by classifying the data of the buffer cache into random data and sequential data in response to an event signal received from a host;
- the storage medium comprising a journaling area for storing the log information, the storage medium storing the random data along with an address information map in the journaling area, and storing the sequential data in an area other than the journaling area.
A cache synchronization method, comprising:
- receiving an event signal from a host;
- storing data of a buffer cache in a storage medium in response to the event signal by classifying the data of the buffer cache into random data and sequential data;
- storing the random data and an address information map in a first area of the storage medium;
- and
- storing the sequential data in a second area in the storage medium.
