The noises at the power lines limit the charge pump to provide large instantaneous current to PCM cells, which results in the number of bits can be written concurrently, i.e. the size of write unit, is restricted in PCM. When implementing PCM as the main memory, the inequality of cache line's size and write unit's size may result in many consecutive… CONTINUE READING
