memristor
n.— «The four passive components of electronics are the resistor, capacitor, inductor and the memristor, which was discovered only a few months ago. Memristors (from memory-resistors, geddit?) are resistors whose resistance depends on their past. In that sense they remember the past or, as an electronics engineer might put it, they store information.» —“Memristors made into low cost, high density RRAM (Resistive Random Access Memory)” by KFC the physics arXiv blog Jan. 9, 2009.

By the definiation of this article, they should include inductors with ferrite cores as a separate passive component. It also has hysteresis, and was the static memeory device of early computers. See “core memeory”, so named because it used ferrite cores, not necessarily because it was the most fundamental memory in a system.
