Embedded Flash technologies and their applications: Status & outlook

In the last two decades embedded Flash technologies took over a dominating role in several IC market segments. Two key application areas driving leading edge embedded Flash technologies and forming the majority of the corresponding market volume are automotive microcontrollers (µCs) and smartcards. This paper gives an overview of these technologies, their applications, requirements, key challenges as well as future outlook.

Analysis and optimization of program disturb in split-gate cells using source side injection and impact on further cell size reduction

Program disturb is a major issue limiting the functionality of hot carrier programmed flash memories. This paper reports a detailed characterization of program disturb in a split-gate flash memory cell using source side injection programming. Key parameters influencing the cells disturb sensitivity have been investigated, empirical models have been developed and a physical root cause has been identified. Conclusions for cell operation and cell size reduction capabilities are drawn.
