This book provides a comprehensive introduction to embedded flash
memory, describing the history, current status, and future projections
for technology, circuits, and systems applications. The authors describe
current main-stream embedded flash technologies from floating-gate 1Tr,
floating-gate with split-gate (1.5Tr), and 1Tr/1.5Tr SONOS flash
technologies and their successful creation of various applications.
Comparisons of these embedded flash technologies and future projections
are also provided. The authors demonstrate a variety of embedded
applications for auto-motive, smart-IC cards, and low-power,
representing the leading-edge technology developments for eFlash. The
discussion also includes insights into future prospects of
application-driven non-volatile memory technology in the era of smart
advanced automotive system, such as ADAS (Advanced Driver Assistance
System) and IoE (Internet of Everything). Trials on technology
convergence and future prospects of embedded non-volatile memory in the
new memory hierarchy are also described.
- Introduces the history of embedded flash memory technology for
micro-controller products and how embedded flash innovations
developed;
- Includes comprehensive and detailed descriptions of current
main-stream embedded flash memory technologies, sub-system designs and
applications;
- Explains why embedded flash memory requirements are different from
those of stand-alone flash memory and how to achieve specific goals
with technology development and circuit designs;
- Describes a mature and stable floating-gate 1Tr cell technology
imported from stand-alone flash memory products - that then introduces
embedded-specific split-gate memory cell technologies based on
floating-gate storage structure and charge-trapping SONOS technology
and their eFlash sub-system designs;
- Describes automotive and smart-IC card applications requirements and
achievements in advanced eFlash beyond 4
0nm node.
