Abstract

Disclosed is a non-volatile memory device and a method of programming the same. The non-volatile memory device is programmed by applying a wordline voltage, a bitline voltage, and a bulk voltage to memory cells within the device. During a programming operation for the device, the bulk voltage is generated by a first pump. However, where the bulk voltage exceeds a predetermined detection voltage, a second pump is further activated in order to lower the bulk voltage.
