Structures, methods, and systems for ferroelectric memory transistors

Integrated memory circuits, key components in thousands of electronic and computer products, have recently been made using ferroelectric memory transistors, which offer faster write cycles and lower power requirements than over conventional floating-gate transistors. One problem that hinders the continued down-scaling of conventional ferroelectric memory transistors is the vulnerability of their gate insulations to failure at thinner dimensions. Accordingly, the inventors devised unique ferroelectric gate structures, one of which includes a high-integrity silicon-oxide insulative layer, a doped titanium-oxide layer, a weak-ferroelectric layer, and a control gate. The doped titanium-oxide layer replaces a metal layer in the conventional ferroelectric gate structure, and the weak-ferroelectric layer replaces a conventional ferroelectric layer. These replacements reduce the permittivity mismatch found in conventional gate structures, and thus reduce stress on gate insulation layers, thereby improving reliability of ferroelectric memory transistors, particularly those with thinner gate insulation.

Demodulation Sensor with Separate Pixel and Storage Arrays

A demodulation image sensor, such as used in time of flight (TOF) cameras, extracts all storage- and post-processing-related steps from the pixels to another array of storage and processing elements (proxels) on the chip. The pixel array has the task of photo-detection, first processing and intermediate storage, while the array of storage and processing elements provides further processing and enhanced storage capabilities for each pixel individually. The architecture can be used to address problems due to the down-scaling of the pixel size. Typically, either the photo-sensitivity or the signal storage capacitance suffers significantly. Both a lower sensitivity and smaller storage capacitances have negative influence on the image quality. The disclosed architecture allows for keeping the storage capacitance unaffected by the pixel down-scaling. In addition to that, it provides a high degree of flexibility in integrating more intelligence into the image sensor design already on the level of the pixel array. In particular, if applied to demodulation pixels, the flexibility of the architecture allows for integrating on sensor-level concepts for multi-tap sampling, mismatch compensation, background suppression and so on, without any requirement to adjust the particular demodulation pixel architecture.

Trim-matched segmented digital-to-analog converter apparatus, systems and methods

One or more high-order bit linear branches of a segmented DAC are implemented as R-2R networks geometrically down-scaled from the DAC binary portion by a selected factor. The resulting increase in closely-located mismatch is compensated for by implementing a trim circuit at a low-order end of each such linear branch. The trim circuit is designed with a number of trim steps to compensate for the selected linear branch down-scaling factor. Each trim step switches a resistance into the low-order end of the linear branch resulting in an even resistance increment or decrement at the lumped linear branch output. The trim circuit is calibrated to provide an amount of trim at the linear branch output such that the lumped resistance of the trimmed linear branch matches the lumped resistance of the binary portion within a selected tolerance (e.g., generally + / −0.5 LSB).
