Abstract:
The memory controller forms temporary virtual blocks each composed of a plurality of physical blocks, whose physical addresses are the same value, each of which is included in each of flash memories, extracts temporary virtual block to which at least one defective block belongs from the temporary virtual blocks, generates a second temporary virtual block to which a defective block does not belong by replacing a defective block belonging to one temporary virtual block with a normal block belonging to another temporary virtual block among temporary virtual blocks extracted, and allocates temporary virtual blocks not extracted and second temporary virtual blocks generated to available virtual blocks.
