The invention pertains to methods and compositions for treating medical disorders characterized by elevated levels or abnormal expression of TNF\u03b1 by administering a TNF\u03b1 antagonist, such as recombinant TNFR:Fc. In an example, a method may include identifying mask logic for masking cells in the phase change memory array and routing the mask logic to the cells. The management device acquires electric energy consumption of the one or more energized parts and controls the operational state of the one or more energized parts so that the electric energy consumption of the storage device over a predetermined period does not exceed a prescribed upper limit.
