Abstract: A controller includes a host command sensor suitable for generating a target ratio between first typed host commands and second typed host commands; an output command generator suitable for generating first and second typed output commands respectively corresponding to the first and second typed host commands; and an arbiter suitable for sequentially transmitting the first and second typed output commands from the output command queue to a channel, and generating a channel ratio between first and second typed output commands transmitted from the output command queue to the channel. The arbiter transmits one of the first and second typed output commands from the output command queue to the channel by comparing the channel ratio with the target ratio.

Abstract: A memory system includes: a memory device including a plurality of memory blocks configured to store data; and a controller configured to determine a power level for an operation corresponding to a command received from a host, and provide the determined power level to a memory block which is subject to the operation.

Abstract: A memory system may include: a memory device including a plurality of pages, each page including a plurality of memory cells coupled with a word line, a plurality of memory blocks in which the pages are included, a plurality of planes which include the memory blocks, and a plurality of memory dies in which the planes are included; and a controller suitable for performing at least one of a foreground operation and a background operation for the memory blocks, for checking parameters of the respective memory blocks in correspondence to performing the at least one of the foreground operation and the background operation, generating normalized parameters of the respective memory blocks, and performing the foreground operation and the background operation by using the normalized parameters of the respective memory blocks.
