Abstract: The present invention provides a control method of a flash memory controller is disclosed, wherein the flash memory controller is configured to access a flash memory module, and the control method comprising: allocating a memory space within a memory for storing data from the host device; dividing the memory space into a plurality of zone buffers, wherein each of the zone buffers is used to store data corresponding to one zone having an opened state; and for a first zone buffer of the plurality of zone buffers, controlling a first buffer and a second buffer within the first zone buffer to alternately store data of a first zone from the host device and write the data of the first zone to a zoned namespace of the flash memory module.

Abstract: A method of a storage device controller includes: using an interface circuit for receiving and storing different write address information of different write command signals sent from a host device, the different write address information being out of sequence; and, using multiple processor cores to rearrange the different write address information in sequence and then write data into at least one storage zone according to the different write address information rearranged in sequence.
