Abstract
Preselection methods in which unstable bitcells
are discarded are widely used to enhance the stability of the
physical unclonable function (PUF). If the discard range of
the preselection is too narrow, all unstable bitcells cannot be
discarded, whereas, if the discard range is too wide, the PUF
circuit area increases because the number of redundant bitcells
should increase. Moreover, the discard range of most previous
PUFs is not determined by theoretical analysis but rather by
repeated measurem
