Abstract
A method includes automatically charging a capacitor coupled to a battery configured to power a memory through a charge switch that is closed whenever a voltage of the battery exceeds a recovery trip voltage or exceeds a shutdown trip voltage but is less than the recovery trip voltage and opened whenever the voltage of the battery drops below the shutdown trip voltage such that a minimum voltage of the shutdown trip voltage is maintained on the battery, thereby enabling the memory to retain information therein. The method also includes rendering a stored energy of the capacitor available to all circuitry coupled to the battery following the charging thereof through coupling the capacitor in parallel with the battery based on closure of a discharge switch following the charging of the capacitor.
