Abstract
To maintain stability of memory array operations, a current source supplies a common source line of a memory. The magnitude of the regulation current from the source is dynamically determined based on the amount of current from the array itself through use of a feedback control signal provided by a current comparator circuit. The current comparison circuit can use either a digital or an analog implementation.
