Original Abstract Submitted

Disclosed are methods, systems, and apparatuses for semiconductor memory devices (e.g., dynamic random access memory (DRAM)) that include a command/address inversion (CAI) input signal indicating whether command/address inputs to the memory devices are inverted. The CAI input signal may be generated by a memory controller, a registering clock driver (RCD), or other component coupled to the memory devices, and the component may generate the CAI input signal differently for the different memory devices to which the component is coupled. As described herein, the component may dynamically generate the CAI input signal based on the values of the command/address inputs so as to reduce power consumption by the memory devices while retaining signal integrity.
