A process for biomass catalytic cracking is described herein. When the chip enable signal CEN indicates that the integrated circuit memory 10, 12 is disabled, then power control circuitry 38 serve to switch portions of the integrated circuit memory 10, 12, such as word line driver circuitry 24, sense amplifiers 22 and buffer circuitry 30, into a low power state from an operating state. For example, adaptive resource access priority allocation may include increasing the priority for graphical data transfer during intervals of high demand for memory andor bus bandwidth resources.
