MEMORY MANAGEMENT APPARATUS, VIDEO RECORDING AND REPRODUCING APPARATUS, MEMORY MANAGEMENT METHOD, VIDEO RECORDING AND REPRODUCING METHOD, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a memory management apparatus, a video recording and reproducing apparatus, a memory management method, a video recording and reproducing method, and a computer program capable of suppressing deterioration in use efficiency of a NAND memory.SOLUTION: A memory management apparatus of an embodiment has a storage part and a memory management part. The storage part includes one or more storage media for storing data. The memory management part manages memory blocks included in the storage medium as either normal blocks or bad blocks on the basis of processing time required for writing, reading, or erasing the memory block. The memory management part adjusts a threshold value of the processing time used for determining whether the memory block is the normal block or the bad block according to the processing time of each piece of the processing.SELECTED DRAWING: Figure 3
