A local SONOS structure having a two-piece gate and a self-aligned ONO structure includes: a substrate; an ONO structure on the substrate; a first gate layer on and aligned with the ONO structure; a gate insulator on the substrate aside the ONO structure; and a second gate layer on the first gate layer and on the gate insulator. Each FRU in the hierarchy has a type, and may have a number of subsidiary FRUs. Furthermore, when the toner concentration is changed, the setting of a correction reference of the \u03b3 correction and correction timing of the \u03b3 correction are accordingly changed. Analysis may be performed at the remote site with the results of the analysis communicated to the mobile communication device at the growing point. The device and method has application to MIMO systems. This configuration offers an output voltage with an improved transient characteristic against an abrupt variation in the output current and simultaneously permits reduction of the power consumed when the output current increases.
