Abstract:
The present invention relates to a 3D stacked NAND flash memory array and, more specifically, to a 3D stacked NAND flash memory array having an SSL status check building for monitoring a threshold voltage of string selection transistors, a method for monitoring the threshold voltage of the string selection transistors through the SSL status check building, and a method for driving the 3D stacked NAND flash memory array having the SSL status check building.
