Abstract
One embodiment of a method includes loading, by a memory controller, a boot image from a solid state drive to an operating memory of a computing system during an initialization operation of the computing system. The initialization operation initializes components of the computing system.
Claims19
A method for setting a mode of a storage device including a plurality of memory chips, the method comprising:
- determining whether a number of bad blocks of a first memory chip among the plurality of memory chips is higher than a threshold value;
- setting the first memory chip to a read only mode if the number of the bad blocks is higher than the threshold value;
- and
- storing metadata of the first memory chip set to the read only mode to a second memory chip among the plurality of memory chips if the number of the bad blocks is higher than the threshold value.
A method for initializing a storage device including a plurality of memory chips, the method comprising:
- determining whether an identification number is read from a selected memory chip of the plurality of memory chips;
- reading metadata from the selected memory chip if the identification number is read from the selected memory chip;
- selecting a mode of the selected memory chip according to at least one of the determining whether the identification number is read from the selected memory chip of the plurality of memory chips and the read metadata, the selecting selects the mode of the selected memory chip as an unaccessible mode if the identification number is not read from the selected memory chip;
- and
- determining whether modes of remaining memory chips of the plurality of memory chips are selected.
