A facilitated transport membrane with improved permeance and selectivity to alkene-based unsaturated hydrocarbons is provided. The dicingdie-bonding film is excellent in balance between retention in dicing a work and releasability in releasing its diced chipped work together with the die-bonding adhesive layer. A sleep and shut-off circuit is connected between a virtual supply terminal and a first physical supply terminal to reduce leakage from the cache sub-array when the cache sub-array is disabled in a shut-off mode.
