Abstract
An operating method of a memory device includes receiving a first read command, providing a read voltage to a first memory cell based on the first read command, determining whether the first memory cell is in a set state, and providing a backward pulse to the first memory cell that has been determined to be in the set state.
Claims20
An operating method of a memory device, comprising:
- receiving a first read command;
- providing a read voltage to a first memory cell based on the first read command;
- determining whether the first memory cell is in a set state;
- and
- providing a backward pulse to the first memory cell that has been determined to be in the set state.
2 more elements
A memory device, comprising:
- a memory cell electrically connected between a bit line and a word line;
- a voltage change circuit configured to provide a first voltage to one of the bit line and the word line and configured to provide a second voltage to the other of the bit line and the word line;
- a sense amplifier configured to generate a signal indicating a state of the memory cell;
- and
- a control circuit configured to control the voltage change circuit to provide a read voltage to the memory cell after a start of a read operation and configured to control the voltage change circuit to sequentially provide a backward pulse and a forward pulse to the memory cell based on the state of the memory cell.
