Abstract: Memory devices, systems, and methods that maximize command and address (CA) signal group rate with minimized margin degradation across a channel and associated operating modes are disclosed and described. In one example, the operating mode can be 1 bit per 1.5 clock cycles.

Abstract: Apparatus and method to vary the strength with which a signal transmitted by a driver circuit of a transmitting device to a receiving circuit across a conductor such that a transmitted voltage level is driven onto a conductor with a reduced strength where adjacent binary bits values are of the same value so as to avoid building up capacitive a charge of either an undesirably high or undesirably low voltage level as a result of continuing to drive the same voltage level with the same strength, and such that a transmitted voltage level is driven onto a conductor with a greater strength where the voltage level now being transmitted differs from the previous voltage level so as to overcome the capacitive charge of the previous voltage level that may have built up, more quickly.
