Abstract
A data recording system includes a file system configured to manage block-based input/output of data, a phase-change random access memory (PRAM) configured to write first data among the data in units of sub blocks, and a block abstract layer configured to receive a write command of the first data to a first particular block in the PRAM from the file system and log changed data information to a second particular block in the PRAM in units of sub blocks, and a method to provide the same.

A data recording system comprising:
- a file system configured to manage block-based input/output of data;
- a phase-change random access memory (PRAM) configured to write first data among the data in units of sub blocks;
- and
- a block abstract layer configured to receive a write command of the first data to a first particular block in the PRAM from the file system and log changed data information to a second particular block in the PRAM in units of sub blocks.
A data recording system comprising:
- a file system configured to manage block-based input/output of data;
- a phase-change random access memory (PRAM) configured to write first data among the data in units of sub blocks;
- and
- a block abstract layer configured to receive a write command of the first data to a first particular block in the PRAM from the file system, log data of the first particular block to a second particular block in the PRAM, and record changed data information in the first particular block in the PRAM in units of sub blocks.
A method of recording data in a recording system, comprising:
- receiving a write command from a file system to write first data among block-based data in a phase-change random access memory (PRAM) in units of sub blocks;
- and
- writing the first data to a first particular block in the PRAM and to log changed data information to a second particular block in the PRAM in units of sub blocks.
