The quest for a solid state universal memory with high-storage density, high read/write speed, random access and non-volatility has triggered intense research into new materials novel device architectures. Though the non-volatile market is dominated by flash now, it very low operation speed ~10 μs programming ms erasing time. Furthermore, can only withstand ~10(5) rewriting cycles, which prevents from becoming memory. Here we demonstrate that significant photovoltaic effect of ferroelectric...
