First Claim
Patent Images
1. 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.
