摘要
An irreproducible and re-emergent unique structure or pattern identifier manufacturing and detection method, system, and apparatus are provided. A non-volatile floating gate charge storage device can include a block of floating gate transistors that can include a semiconductor region, a source region, a drain region, a floating gate region, a tunnel oxide region, an oxide-nitrite-oxide region, and a control gate region. A structure altering stress effect is applied to the block of transistors to create a passage region in a random number of floating gate regions of floating gate transistors which changes charge storage or electrical characteristics of random elements of the block of transistors. The passage region alters charges on a floating gate region to escape in a different manner than pre-alteration form causing the floating gate region to lose its charge. An apparatus for recording and detecting such differences in pre and post alteration can also be provided.
