    Abstract: A wireless communication device (UE) may include random access memory and associated software configured to selectively place different memory banks into either an active power on mode, retention mode, or power off mode. The selective placement of memory banks into different modes may be performed based on a variety of factors including software module voting information, a current power mode of the memory banks, one or more software program(s) and/or data currently stored on the memory banks, and a counter that counts an amount of time during which a memory bank is not accessed. The placement of memory banks into different modes may be controlled by a memory controller coupled to the memory banks.
