PROBLEM TO BE SOLVED: To provide a method, system and apparatus for performing memory maintenance and calibration operations. SOLUTION: To perform calibration operations, calibration data may first be written to memory, and subsequently read back. The calibration operations may then be performed in response to detecting discrepancies between the data written and data read back from memory. In an embodiment of the invention, to prevent the calibration data from being altered during memory maintenance operations, skipping of sections containing calibration data is performed during the memory maintenance operations. Therefore, the calibration data is preserved so as to enable appropriate calibration operation. COPYRIGHT: (C)2008,JPO&INPIT
