Abstract
A method for controlling a precharge timing of a memory device is disclosed. The method includes making timing of generation of a signal for determining a precharge timing in a normal operation and a signal for determining a precharge timing in a refresh operation different from each other by making timing of generation of a signal for controlling the normal operation and a signal for controlling the refresh operation different from each other.
Claims12
A method for controlling a precharge timing of a memory device, comprising the step of making timing of generation of a signal for determining a precharge timing in a normal operation and a signal for determining a precharge timing in a refresh operation different from each other by making timing of generation of a signal for controlling the normal operation and a signal for controlling the refresh operation different from each other.
A method for controlling a precharge timing of a memory device, comprising the steps of:
- generating first and second pulse signals for controlling a precharge operation;
- receiving the first pulse signal and generating a third pulse signal in a normal operation while receiving the second pulse signal and generating a fourth pulse signal in a refresh operation;
- and
- receiving the third and fourth pulse signals and outputting a precharge signal for controlling a precharge timing of the memory device.
An apparatus for controlling a precharge timing of a memory device, comprising:
- a control signal generator for generating first and second pulse signals for controlling a precharge operation;
- an auto precharge controller for receiving the first signal and operating in a normal operation;
- a refresh controller for receiving the second signal and operating in a refresh operation;
- and
- a precharge pulse generator for outputting a signal for determining a precharge timing of the memory device in response to an output signal of the auto precharge controller or an output signal of the refresh controller.
