Abstract
An integrated circuit device includes a controller, a voltage source coupled to the controller, a voltage sampler coupled to the controller, a to current detector coupled to the controller and memory coupled to the controller, where memory includes code segments executable by the controller for: (a) measuring a cell voltage to determine an initial voltage; (b) holding the cell voltage at the initial voltage using a power source; and (c) determining the leakage current of the cell by the current provided by the current power source with a low current detector. The power source can be one or both of a voltage source and a current source.
