Vertical 3D Memory Technologies

Acknowledgments

I would like to thank all of those who contributed information and offered suggestions for this book. In particular I would like to thank my husband, Joe Hartigan, who put up with the long hours spent writing it and who used his experience as a memory engineer to check the facts in Chapter 1. I would also like to thank the many engineers and researchers throughout the memory industry who gave me permission to use their material in this book.

I would like to thank David Prince, my colleague at Memory Strategies International and my son, who spent time helping gather information for this book, discussing its content with me, and reading it carefully. David's background in physics as well as his years spent teaching physics helped in checking the accuracy and readability of the entire manuscript.

I would like to thank Dr. Chih-Yuan Lu of Macronix for his encouragement during the writing of the book, for modifying his figure for use on the cover of the book, and for his permission to use many of the figures in Chapter 4. I would also like to thank Dr. Andrew Walker of Schiltron for reading and commenting on Chapter 4, for suggesting additional technical references to enhance the book, and for permission to use material from his published critical analysis of vertical memories in Chapter 3.

Dr. Stephan Menzel, of the Forschungszentrum Jülich, deserves special mention for his very careful reading of the material in Chapter 5, for his many helpful suggestions, detailed ...
