Abstract
An embodiment of the invention provides a method for decreasing power in an L1 program memory of a multi-level memory system. The power is decreased by enabling a sleep mode in the L1 program memory. The sleep mode determines when the L1 program memory will not be accessed for a period of time. When it is determined that the L1 program memory will not be accessed for a period of time, the voltage applied to the memory array is reduced. When it is determined that the L1 program memory will be accessed, the voltage applied to the memory array is increased.
