An apparatus and method for improving memory cell reliability is disclosed. The process uses a single-site catalyst that contains a boraaryl ligand. The process of preparing the compounds and their application as compositions with pharmacological properties and herbicides of interest are described. Therefore, the benefits of the prior art are achieved at a reduced cost by eliminating a barrier and manufacturing steps associated with the provision of a barrier, as is conventional. The timing controller outputs a plurality of training packets to the source drivers. The tetracyclic ringsystem having cis-fused five and seven membered rings is formed in a base-catalysed cyclization reaction.
