A simple nanoimprinting method creates arrays of ferroelectric polymer structures suitable for low-cost, non-volatile memories. With the development of nanoimprinted high-quality ferroelectric nanomesa arrays, it seems that we now have all the necessary ingredients to print inexpensive, disposable organic memory chips. Figure 1. The nanoimprinting method and the two ways it can be used in non-volatile random-access memory and data-storage devices. a, A nanoimprinting mould embosses the polymer by hot pressing, leaving a well-ordered array of ferroelectric nanomesas. b, A cross-point memory, which is addressed by “word line” contacts on the bottom and “bit line” contacts on top. c, A multiprobe array.
