  • Control of inputs to a memory device
    Patent number: 9042195
    Abstract: A memory device includes a command decoder and control interface logic. One or more external inputs, such as row and column address strobes, communicate with the command decoder through the control interface logic. A control signal is also in communication with the control interface logic. During operation of a drowsy mode in the memory device, a self-refresh signal causes the control signal to disable the external inputs. With the external inputs disabled, command hazards are reduced when exiting drowsy mode.
