    Abstract: In some embodiments, a system may include a sub-hierarchy clock control. In some embodiments, the system may include a master unit. The master unit may include an interface unit electrically coupled to a slave unit. The interface unit may monitor, during use, usage requests of the slave unit by the master unit. In some embodiments, the interface unit may turn off clocks to the slave unit during periods of nonuse. In some embodiments, the interface unit may determine if a predetermined period of time elapses before turning on clocks to the slave unit such that turning off the slave unit resulted in the system achieving greater efficiency. In some embodiments, the interface unit may maintain, during use, power to the slave unit during periods of nonuse. The interface unit may maintain power to the slave unit during periods of nonuse such that data stored in the slave unit is preserved.
