Abstract
The present disclosure relates to method of operating a memory device, the memory device includes a memory cell array, a voltage generator, and control logic. The voltage generator configured to increase a power supply voltage. The control logic is configured to store a time based on the increased power supply voltage and a reference voltage. The reference voltage is a voltage level used to perform an operation on the memory cell array.
Claims20
A memory device, comprising:
- a memory cell array comprising at least one memory block;
- a voltage generator configured to receive a power supply voltage and increase the power supply voltage until the increased power supply voltage is equal to or greater than a reference voltage;
- and
- a control logic configured to initiate, at a first time, when the voltage generator begins increasing the power supply voltage and store a second time corresponding to when the increased power supply voltage is equal to or greater than the reference voltage,
- wherein the reference voltage is a voltage level used to perform an operation on the memory cell array, and
- wherein the voltage generator controls a time consumed to reach the reference voltage from the power supply voltage based on a duration of time that elapses from the first time to the second time.

A method of operating a memory device including a memory cell array, the method comprising:
- increasing a power supply voltage on the basis of a voltage generating signal;
- generating a comparison signal by comparing an increased voltage with a reference voltage when the power supply voltage is increased;
- and
- storing a state change time of the comparison signal,
- wherein the reference voltage is a voltage level used in performing an operation on the memory cell array, and
- wherein a time consumed to reach the reference voltage from the power supply voltage is controlled based on a duration of time that elapses from the first time to the second time.
