NON VOLATILE MEMORY DEVICE AND OPERATING METHOD THEREOF

摘要

PURPOSE: A non-volatile memory device and an operation method thereof are provided to set an optimized program initial voltage in a program operation for a second page by using the program result for a first page. CONSTITUTION: Latch units(1422, 1432, 1442) store program object data or erase object data. A one bit pass decision unit(1490) decides a program object cell which is programmed with verification voltage by grounding or floating a second verification signal terminal according to the data set in a second node of the latch units or the data applied to a detection node. The one bit pass decision unit includes first and second switching components connected in parallel between the ground terminal and the second verification signal terminal.
