Patent ID: 11961562
Assignee: YANGTZE MEMORY TECHNOLOGIES CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 13:
14. The memory device of claim 9, wherein the comparing circuit comprises a first input of a voltage portion proportional to the word line voltage and a second input of a reference signal coupled to the control logic, the flag signal being a difference between the voltage portion and the reference signal, wherein the control logic is configured to:
apply a first step voltage on the second input of the comparator, the first step voltage being equal to the second voltage;
obtain the first value from the sensing device;
in response to the flag signal turning from 1 to 0, apply a second step voltage on the second input of the comparator, the second step voltage being equal to the third voltage and greater than the first step voltage; and
obtain the second value from the sensing device.
