Abstract: In a method of operating a memory system disclosed, whether a first condition is satisfied is determined. The first condition is associated with free blocks and garbage collection (GC) target blocks from among a plurality of memory blocks. In response to the first condition being satisfied, a size of a data sample associated with executions of a host input/output request and GC is adjusted. The data sample is generated based on the adjusted size of the data sample. The data sample includes a downscaled current valid page count (VPC) ratio and the first number of previous host input/output request to GC processing ratios. A current host input/output request to GC processing ratio is calculated based on the data sample. The host input/output request and the GC are performed based on the current host input/output request to GC processing ratio.

Abstract: A method of operating a memory system includes; storing data in a buffer region of the nonvolatile memory, later issuing a migration request directed to the data stored in the buffer region and executing a migration operation to move the data from buffer region to a main region of the nonvolatile memory device. Upon completion of the migration operation, marking a migration operation completion time, and after an initial verify shift (IVS) time has elapsed following the migration operation completion time, updating a mapping table associated with the data in view of the executed migration operation.

Abstract translation: 一种操作存储器系统的方法包括： 将数据存储在非易失性存储器的缓冲区域中，随后发出针对存储在缓冲区域中的数据的迁移请求，并执行迁移操作，以将数据从缓冲区域移动到非易失性存储器件的主区域。 在迁移操作完成时，标记迁移操作完成时间，并且在迁移操作完成时间之后经过初始验证移位（IVS）时间之后，考虑到所执行的迁移操作，更新与数据相关联的映射表。
