Abstract
An electronic device includes a semiconductor memory. The semiconductor memory includes a bit line, a word line crossing the bit line, and a memory cell coupled to and disposed between the bit line and the word line. In a read operation, when the word line, which is in a precharged state, is floated, the bit line is driven to increase a voltage level of the bit line, and stopped when the memory cell is turned on.
Claims20
A method of operating an electronic device including memory cells, the method comprising:
- precharging a selected word line associated with a memory cell;
- floating the selected word line;
- driving a selected bit line to increase a voltage level of the selected bit line, the selected bit line being associated with the memory cell;
- and
- stopping the driving of the selected bit line when the memory cell is turned on.
A method of operating an electronic device including memory cells, the method comprising:
- precharging a selected local word line;
- floating the selected local word line;
- turning on a selected local switch to apply a read voltage to a selected memory cell through a selected local bit line, the selected memory cell being coupled to and disposed between the selected local word line and the selected local bit line, the selected local switch coupling the selected local bit line to a global bit line;
- and
- turning off the selected local switch when the selected memory cell is turned on by the read voltage.
An electronic device including a semiconductor memory, the semiconductor memory comprising:
- a bit line;
- a word line crossing the bit line;
- and
- a memory cell coupled to and disposed between the bit line and the word line,
- wherein, in a read operation, when the word line, which is in a precharged state, is floated, the bit line is driven to increase a voltage level of the bit line and stopped when the memory cell is turned on.
