MANAGEMENT INFORMATION GENERATING METHOD, LOGICAL BLOCK CONSTRUCTING METHOD, AND SEMICONDUCTOR MEMORY DEVICE |
摘要 |
A management information generating method wherein logical and physical block addresses (BAs) of continuous addresses are associated with each other in the BA translation table. When a logical block is constructed, an allowable value is set for the number of defective physical blocks. A logical block having fewer defects than the set number is set usable, and a logical block having more defects than the set number is set unusable. System logical block construction is performed to preferentially select physical blocks from a plane list including a large number of usable blocks to equalize the number of usable blocks in each plane list. It is determined whether the number of free blocks is insufficient on the basis of a first management unit and whether the storage area for the indicated capacity can be reserved on the basis of the management unit different from the first unit.
