    Abstract: A method of a flash memory device to be used in a storage device and coupled to a flash memory controller of the storage device through a specific communication interface, the flash memory device comprising an input/output (I/O) control circuit, a command register, an address register, a memory cell array at least having a first plane and a second plane which is different from the first plane, at least one address decoder, and a control circuit having a specific buffer, and the method comprises: buffering command information of a command signal, sent from the flash memory controller and transmitted through the I/O control circuit, into the command register; buffering address information of the command signal, sent from the flash memory controller and transmitted through the I/O control circuit, into the address register; and controlling the specific buffer storing a transmission history information of the specific communication interface.

    IPC: G06F3/06

    Abstract: A flash memory controller is used in a storage device and coupled to a flash memory device of the storage device through a specific communication interface and includes an input/output (I/O) circuit and a processor. The I/O circuit is coupled to the flash memory device through the specific communication interface, and used for sending commands and data between the flash memory device and the processor. The processor is used for controlling the I/O circuit sending a specific boundary check command signal or a specific boundary check set-feature signal via the specific communication interface to the flash memory device, to make the flash memory device read out more page data of multiple page units from a specific block in the memory cell array and to make the flash memory device determine whether the multiple page units are empty pages.
