Abstract

Aspects for program pulse generation during programming of nonvolatile electronic devices include providing a configurable voltage sequence generator to manage verify-pulse and pulse-verify switching as needed during modification operations of a programming algorithm for nonvolatile electronic devices, wherein more efficient modification operations result. In this manner, highly flexible bit sequence generation that can be easily managed by a microcontroller occurs, resulting in a shorter code length, a faster execution time, and ease of reuse in different devices. More particularly, fully compatible voltage sequence generation is introduced that can be applied on the terminals of the flash cells being modified and permits an efficient and time saving management of pulse-verify and verify-pulse switching.
