Abstract:
There are provided a memory device and an operating method thereof. A memory device includes: a peripheral circuit for decreasing threshold voltages of memory cells included in a selected memory block and then performing an erase verify operation for detecting a threshold voltage distribution of the memory cells, wherein the peripheral circuit applies an erase pulse to a well, bit lines or source line in which the selected memory block is included a preset number of times; and a control logic for outputting a voltage setup code according to the threshold voltage distribution of an erase status, which is detected by the erase verify operation.

Claim (Index 23):
The method of  claim 16 , wherein the setting of the program verify voltage includes:\n performing an erase verify operation, using a gradually increased erase verify voltage; when the erase verify operation passes, storing erase status information in the selected memory block according to the erase verify voltage used in the passed erase verify operation; outputting a voltage setup code, based on the erase status information, in a program operation; and setting the program verify voltage according to the output voltage setup code.
