Abstract
A memory system includes: a memory device; a host interface suitable for receiving write commands and queueing the received write commands in an interface queue; a workload manager suitable for detecting, in a cache program mode, a mixed workload when a read count is greater than a first threshold value, the read count representing a number of read commands queued in the interface queue and the mixed workload representing receipt of a mix of read and write commands; a mode manager suitable for switching from the cache program mode to a normal program mode when the mixed workload is detected; and a processor suitable for processing write commands queued in a command queue in the cache program mode and processing write commands queued in the interface queue in the normal program mode when the mixed workload is detected.
