Abstract
The present invention provides a method of reducing current of a memory in a self-refreshing mode and a related memory. The memory includes a word line driver and a controller, and the word line driver includes a transistor. The transistor has a control terminal, a first terminal coupled to a word line, and a second terminal. The method includes: after the memory enters the self-refreshing mode: controlling a voltage difference between the control terminal and the second terminal to correspond to a first value during a self-refreshing operation period; and controlling a voltage difference between the control terminal and the second terminal to correspond to a second value smaller than the first value during a non self-refreshing operation period.
Claims11
A method of reducing current of a memory in a self-refreshing mode, the memory including a word line driver, the word line driver including a transistor having a control terminal, a first terminal coupled to a word line, and a second terminal, the method comprising:
- after the memory enters the self-refreshing mode:
- controlling a voltage difference between the control terminal and the second terminal to correspond to a first value during a self-refreshing operation period;
- and
- controlling a voltage difference between the control terminal and the second terminal to correspond to a second value smaller than the first value during a non self-refreshing operation period.
A memory, comprising:
- a word line driver, comprising a transistor having a control terminal, a first terminal coupled to a word line, and a second terminal;
- and
- a controller, for controlling a voltage difference between the control terminal and the second terminal to correspond to a first value during a self-refreshing operation period after the memory enters a self-refreshing mode, and controlling a voltage difference between the control terminal and the second terminal to correspond to a second value smaller than the first value during a non self-refreshing operation period after the memory enters the self-refreshing mode.
