Abstract: Numerous embodiments are disclosed for a high voltage generation algorithm and system for generating high voltages necessary for a particular programming operation in analog neural memory used in a deep learning artificial neural network. Different calibration algorithms and systems are also disclosed. The system can modify a high voltage signal applied to an array of cells during a programming operation as the number of cells being programmed changes.
