Charge pumps, voltage regulators and HV switches

Abstract

Modifying or reading the number of electrons stored into the floating gate requires a big set of voltages. The high voltage (HV) system has to provide all these voltages with the desired precision, timing and granularity. On top of that, many voltages have a value greater than the NAND power supply VDD, asking for an on-chip charge pump. This chapter deals with the HV basic building blocks. © 2010 Springer Science+Business Media B.V.
