发明名称 Dual channel memory architecture having reduced interface pin requirements using a double data rate scheme for the address/control signals
摘要 Apparatuses and methods for dual channel memory architecture with reduced interface pin requirements are presented. One memory architecture includes a memory controller, a first memory device coupled to the memory controller by a shared address bus and a first clock signal, and a second memory device coupled to the memory controller by the shared address bus and a second clock signal, where the polarity of the second clock signal is opposite of the first clock signal. A method for performing data transactions is presented. The method includes providing addressing signals over a shared address bus to a first memory device and a second memory device, providing clock signals to the memory devices which are reversed in polarity, where the clock signals are derived from a common clock signal, and transferring data to the memory devices over separate narrow data buses in an alternating manner based upon the clock signals.
