Modern video applications such as video codecs are memory-intensive. As an emerging non-volatile memory technology, phase change memory (PCM) will benefit video applications due to its high density, low leakage power and superior scalability. However, PCM consumes high write energy and can only sustain a limited write number. Hence it is necessary to reduce the write number of PCM for video applications. In this paper, we propose SoftPCM to enhance both energy efficiency and lifetime of PCM… CONTINUE READING
