Abstract
A data arrangement method of a flash memory, a flash memory storage device, and a flash memory control circuit unit are provided. The method may be applied to a flash memory, an embedded memory device, or a solid-state disk having a three-dimensional (3D) structure. The method includes: executing a background garbage collection operation in a background mode; receiving at least one write command from a host when the background garbage collection operation is not completed to suspend the background garbage collection operation and exit the background mode; executing the at least one write command; and entering the background mode and continuing the execution of the background garbage collection operation after the at least one write command is completed. Therefore, execution efficiency of the write command in a foreground mode may be optimized.
