发明名称 Integrated circuit memory devices having data selection circuits therein which are compatible with single and dual rate mode operation and methods of operating same
摘要 Integrated circuit memory devices include first and second memory banks, first and second local data lines electrically coupled to the first and second memory banks, respectively, and a multiplexer having first and second inputs electrically coupled to first and second data bus lines, respectively. A data selection circuit is also provided which routes data from the first and second local data lines to the first and second data bus lines, respectively, when a selection control signal is in a first logic state and routes data from the second and first local data lines to the first and second data bus lines, respectively, when a selection control signal is in a. second logic state opposite the first logic state. A control signal generator is also provided. This control signal generator generates the selection control signal in the first and second logic states when a first address in a string of burst addresses is even and odd, respectively.
