Claim 10:
11. The read operation method according to claim 10, wherein the determining, according to the number of bits of a data change between previous read data and the current read data, whether to invert the current read data to output global bus data for transmission through a global bus and inversion flag data for transmission through an inversion flag signal line comprises:
determining change flag data according to the change between the current read data and the previous read data; and
outputting inverted data of the current read data as the global bus data and setting the inversion flag data to High if number of bits of high data in the change flag data is greater than a preset value, and outputting original current read data as the global bus data and setting the inversion flag data to Low if the number of bits of the high data in the change flag data is less than or equal to the preset value.
