The present disclosure is directed to methods and systems for providing a distributed radio communications network. The memory also includes at least two sub-arrays each having an instance of all of the bit lines of the memory and a portion of the word lines of the memory. The lithium secondary battery is excellent in reliability and can be produced at low processing costs. The power management unit is further configured to clock-gate the memory controller responsive to clock-gating the communication hub and determining that a memory coupled to the memory controller is in a first low power state. At the same time, other functional blocks that are not being heavily utilized and thus have lower performance requirements can be kept at a relatively low power consumption level.
