A semiconductor device includes a substrate having a plurality of diffusion regions defined therein to form first and second p-type diffusion regions, and first and second n-type diffusion regions, with each of these diffusion regions electrically connected to a common node. Each anti-fuse circuit comprising an anti-fuse connected in a series with a blow or control transistor and a control circuit for monitoring the status of the anti-fuse, Control circuit provides an on signal to the gate of control transistor only when a_select_ signal is received at an input of control circuit and if anti-fuse has not been blown. The first API call requests first entities corresponding to a campaign management entity. The determined storage device weight values are used to select one of the storage devices as the target storage to which data from the source storage is migrated. The example system also includes a threshold logic configured to determine that the threshold condition has been met without receipt of a clearance notification from the patient. The special data symbol resides between the preamble or header and the payload and is usable by the second PLC device for processing of the payload.
