An example apparatus includes an array of memory cells coupled to an array power supply and a controller. The controller may be configured to cause a data value to be stored in at least one memory cell of the array of memory cells while the array of memory cells is operating in a first power state and a determination to be made that a change in a power status to a computing system coupled to the array of memory cells has occurred, wherein the change in the power status of the computing system is characterized by the computing device operating in a reduced power state. Responsive to the determination, the controller may be configured to cause the array power supply to be disabled to operate the array of memory cells in a second power state.
