We present the first-ever commercially available microcontroller families built with innovative split-gate based NOR flash memory that uses silicon nanocrystals as the storage medium. The 32-bit mixed-signal low-power Kinetis microcontroller families have nanocrystal based flash memories (referred to as TFS for ‘Thin Film Storage’) with a wide range of array sizes from 32KB to 1MB. In addition, the...
We show a 90nm nanocrystal-based split gate embedded flash memory that is able to meet the speed, endurance and reliability requirements for 32-bit microcontroller products. A 3.4V operating window is achievable and the process is robust and repeatable across many lots. Erase after 10k cycles can be achieved in 5ms, long-term data retention of cycled arrays is not susceptible to SILC-induced charge...
This paper reports on recent bitcell optimizations that improve drive current and program performance. The 16 Mb and 32 Mb array results are best to-date for nanocrystal memories and suggest a robust, reliable array operation.
This paper describes a new method for reconstructing cross-sectional images of an object at arbitrary height and arbitrary angled planes. This method, called the geometric projection method, can produce cross-sectional images for arbitrary planes using only those images acquired from the focal plane of an object. This paper develops the mathematical formulae for the image reconstruction of arbitrary...
