<p>A method of inspecting an array of memory blocks with page breaks disposed between them. The memory array is imaged with a sensor. Pixels of the image within a boundary distance of a horizontal single line of pixels are inspected to determine horizontal edges of the memory blocks to an accuracy of a single pixel. Pixels of the image within a boundary distance of a vertical single line of pixels are inspected to determine vertical edges of the memory blocks to an accuracy of a single pixel. An image of a first and second memor block are compared on a pixel by pixel basis to determine differences and the differences are flagged as potential memory block defects. Images of the page breaks are compared and the differences are flagged as potential page break defects.</p> |
