Abstract
Provided herein may be a memory device and a method of operating the same. The memory device may include a plurality of memory cells, a peripheral circuit configured to perform a verify operation that identifies threshold voltages of the plurality of memory cells by using a first verify voltage and a second verify voltage, and a program operation controller configured to control the peripheral circuit, after the verify operation is terminated and during a period in which a program voltage is applied to the plurality of memory cells, to apply a first control signal to a page buffer that is coupled to a first memory cell having a threshold voltage that is higher than the first verify voltage and lower than the second verify voltage, and apply a second control signal having a lower level voltage than the first control signal to the page buffer.
