  Embedded systems or micro controller based modules have become increasingly
prevalent in our daily lives. However, the security of embedded devices as well
as the authenticity of hardware has become an increasing concern within the
growing Internet of Things (IoT) space. In this paper we setup an experiment
environment where SLC flash program disturbance is observed. We discovered that
intra-page disturbance is easier to be produced than inter-page disturbance. We
also observed that adjacent pages are paired in (2n, 2n+1) manner, and
disturbance only occurs within a pair. Lastly, we found that as page number
increases from 0 to 63, it becomes more difficult to observe the first bit flip
within a page, and thus more difficult to achieve the disturbance stable state.
