Vertical 3D Memory Technologies (eBook, PDF)

• Format: PDF

Produktbeschreibung

The large scale integration and planar scaling of individual system chips is reaching an expensive limit. If individual chips now, and later terrabyte memory blocks, memory macros, and processing cores, can be tightly linked in optimally designed and processed small footprint vertical stacks, then performance can be increased, power reduced and cost contained. This book reviews for the electronics industry engineer, professional and student the critical areas of development for 3D vertical memory chips including: gate-all-around and junction-less nanowire memories, stacked thin film and double gate memories, terrabit vertical channel and vertical gate stacked NAND flash, large scale stacking of Resistance RAM cross-point arrays, and 2.5D/3D stacking of memory and processor chips with through-silicon-via connections now and remote links later. Key features: * Presents a review of the status and trends in 3-dimensional vertical memory chip technologies. * Extensively reviews advanced vertical memory chip technology and development * Explores technology process routes and 3D chip integration in a single reference

Rezensionen

"In summary, Betty Prince has produced a piece of work that is timely and will undoubtedly become a classic text for 3D memory technologies." (3dincites.com, 30 September 2014)

"As the semiconductor memory industry moves to the third dimension a plethora of competing technologies has arisen each claiming to be the logical, lucrative successor to existing two dimensional versions. The very breadth of these new technologies can be confusing even to experienced industry professionals. Dr Prince's book appears at the right time to remove this confusion by explaining each technology's structure, function and potential advantages in a way that is accessible to both interested spectators and those working in the industry. It provides a welcome solid foundation to anyone interested in understanding the various technologies vying for success in this migration."
