Claim 0:
1. 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, comprising:
an input/output (I/O) control circuit, coupled to the flash memory controller through the specific communication interface;
a command register, coupled to the I/O control circuit, for buffering command information sent from the flash memory controller and transmitted through the I/O control circuit;
an address register, coupled to the I/O control circuit, for buffering address information sent from the flash memory controller and transmitted through the I/O control circuit;
a memory cell array, at least having a first plane and a second plane which is different from the first plane;
a data register, coupled to the memory cell array;
at least one address decoder, coupled to the memory cell array and the data register; and
an address control circuit, coupled to the address register and the at least one address decoder, for controlling the at least address decoder accessing at least one data unit, indicated by the address information transmitted from the address register, for at least one plane of the memory cell array;
wherein the address information is first address information which is used for the first plane and is carried by a single command sequence; the address control circuit is arranged to automatically generate second address information associated with the second plane according to the first address information of the first plane, and then control the at least one address decoder selecting multiple data units at the first plane and the second plane based on the first address information and the second address information in response to the command information buffered in the command register so as to perform an access operation upon the multiple data units at the first plane and the second plane.
