A semiconductor structure includes a matrix, an integrated circuit and a scribe line. Raised isolation regions within a semiconductor region separate parallel active regions. Therefore, the occupation of storage resources is reduced. Various actuation mechanisms are disclosed which are operable on the energy storage mechanism to control the rate of release of the energy stored in the energy storage mechanism. The GHV mechanism thus provides a resulting folded GHV that is current and can be utilized for XORing with an IFAR by performing an XOR operation. ZnO crystal of good quality with a reduced number of crystal defects can be grown on a sapphire substrate.
