摘要： Methods and apparatuses for adjusting data strobe signals are disclosed. An example apparatus may include a control circuit that is configured to receive an address and a strobe signal. The control circuit may further be configured to delay the strobe signal based, at least in part on the address to provide a delayed strobe signal. The example apparatus may further include a sense amplification circuit coupled to the control circuit. The sense amplification circuit may be configured to sense signals responsive, at least in part, to receipt of the delayed strobe signal.

摘要： Apparatuses and methods of providing word line voltages are disclosed. An example apparatus includes a voltage driver and a word line driver. The voltage driver is configured to provide a word line voltage, wherein the word line voltage is a pumped supply voltage responsive to an active mode and the word line voltage is a non-zero voltage less than the pumped supply voltage during a standby mode. The word line driver is coupled to the voltage driver and is configured to drive a respective word line to the word line voltage during the active and standby modes.

摘要： An apparatus and method for reducing power consumption in digital circuits, particularly circuits including a charge pump. A driver may selectively drive a signal line, such as a memory device wordline, between a first voltage, which may be a voltage generated by the charge pump, and a different second voltage. A coupling circuit may be coupled between the signal line and the charge pump to selectively couple the signal line to the charge pump responsive to the signal line being driven from the first voltage to the second voltage. For example, the first voltage may be a voltage generated by the charge pump, and the second voltage may be a voltage having a lesser magnitude. As a result, the voltage on the signal line may be discharged into the charge pump when the voltage of the signal line transitions from the first voltage to the second voltage.
