In this chapter, we assess the progress that has been made in the
ﬁeld of memories employing organic-based molecular or polymer
layers. Such technologies explore the use of low-cost “bottom-
up” approaches (i.e., chemical synthesis, surface functionalization,
molecular self-assembly). Recent ﬁndings show that they may have
some features of interest to mainstream storage technologies within
the next few decades, and on a shorter term address new markets
(plastic electronics, ﬂexible/wearable electronics, etc.).
