Ferroelectric memories

For the past 100 years the electronics industry has needed reliable capacitors. The old electrolytic "condensers" in metal cans have long been replaced with microchips, but as developments in computer memories – whose integrated circuits combine transistors, resistors and capacitors – have accelerated, so has the need for better capacitors and materials to make them. In fact the capacitors take up most of the area in modem memory chips, the resistors and transistors being relatively small.
