Assignee: SK HYNIX INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 11:
12. A method of operating a memory device, the method comprising:
precharging a bit line coupled to a memory cell to a precharge voltage;
precharging a potential of a sensing node coupled to the bit line to a first voltage;
discharging the potential of the sensing node from the first voltage to a second voltage; and
storing data of the memory cell in a latch circuit based on a result of comparing the potential of the sensing node with a reference voltage after the potential of the sensing node is discharged to the second voltage and a predetermined period elapses,
wherein the first voltage is a default voltage for precharging the sensing node to sense a threshold voltage of the memory cell, and
wherein the discharging of the potential of the sensing node includes discharging the default voltage to the second voltage by turning on a transistor coupled between the sensing node and a ground node.
