ABSTRACT:
The present invention relates to storage element. At least one read port is coupled to the storage element and a sensing device is coupled to the read port, where the read port is coupled to the storage element in an isolated manner. The sensing device is adapted to sense a small voltage swing. The sensing device includes two inverters comprising input offset and gain stages.
