Abstract

An apparatus includes logic to determine a discharge drop of a capacitor and to adjust an enablement charge level of the capacitor according to the discharge drop.

Claims (24)

1. An apparatus comprising:

a controller;

at least one capacitor; and

at least one of non-transitory machine memory and circuits comprising logic that when executed by the controller:

measures a first voltage of the at least one capacitor;

begins an operation to at least partially discharge the at least one capacitor;

concludes the operation to at least partially discharge the at least one capacitor;

measures a second voltage of the at least one capacitor at the conclusion of the operation to at least partially discharge the at least one capacitor;

determines a time interval for the operation to at least partially discharge the at least one capacitor;

sets an enablement voltage level for the at least one capacitor based on a rate determined from the first voltage, the second voltage, and the time interval; and

wherein the enablement voltage level is a voltage level the at least one capacitor must charge to before the apparatus enables the at least one capacitor to be used as a power source for a memory backup operation.

2. A hybrid memory module, comprising:

a controller;

a volatile memory;

a non-volatile memory;

at least one capacitor; and

at least one of non-transitory machine memory and circuits comprising logic that when executed by the controller:

measures a first voltage of the at least one capacitor;

begins an operation to at least partially discharge the at least one capacitor;

concludes the operation to at least partially discharge the at least one capacitor;

measures a second voltage of the at least one capacitor at the conclusion of the operation to at least partially discharge the at least one capacitor;

determines a time interval for the operation to at least partially discharge the at least one capacitor;

sets an enablement voltage level for the at least one capacitor based on a rate determined from the first voltage, the second voltage, and the time interval; and

wherein the enablement voltage level is a voltage level the at least one capacitor must charge to before the apparatus enables the at least one capacitor to be used as a power source for a memory backup operation.
