Abstract: A method of managing a bad storage region of a memory device may include detecting a bad page of a selected data block that has failed in one of a program operation, a read operation, and an erase operation on the memory device; and performing a mapping process so that the detected bad page is excluded from a storage region to which data is to be programmed, wherein remaining pages of the selected data block excluding the bad page are allowed to be used as a storage region in a garbage collection operation.

Abstract translation: 管理存储器件的不良存储区域的方法可以包括：检测在存储器件中的程序操作，读取操作和擦除操作之一中失败的所选数据块的坏页面; 并且执行映射处理，使得所检测到的坏页被从要编程的数据的存储区域中排除，其中除了坏页之外的所选数据块的剩余页被允许用作垃圾收集中的存储区域 操作。

Abstract: A method of compressing and storing data may include generating target code words by compressing target data to be stored in a memory device by using an initially set compression algorithm; and/or storing in the memory device the target code words according to a data pattern that is repeated in the target code words. A method of compressing and storing data may include generating target code words by compressing target data to be stored in a memory device by using an initially set compression algorithm; and/or storing in the memory device delta-encoded information obtained by performing delta-encoding on the target code words based on source code words including the data pattern.
