  • Publication number: 20240086692
    Abstract: A semiconductor device may include a non-volatile memory cell structure that may be formed in a back end region of a semiconductor device. The non-volatile memory cell structure may include a floating gate structure in which a portion of a dielectric layer is included between a gate structure and a word line conductive structure. The separation of the gate structure and the word line conductive structure by the dielectric layer results in the gate structure being a floating gate structure. This enables a charge to be selectively stored on the gate structure, even when power is removed from the word line conductive structure. The non-volatile memory cell structure along with a volatile memory cell structure are provided in the back end region of the semiconductor device, such that caching and long-term storage may be performed in the back end region of the semiconductor device.

  • Publication number: 20240074137
    Abstract: A capacitorless dynamic random access memory (DRAM) cell may include a plurality of transistors. At least a subset of the transistors may include a channel layer that approximately resembles an inverted U shape, an ohm symbol (?) shape, or an uppercase/capital omega (?) shape. The particular shape of the channel layer provides an increased channel length for the subset of the transistors, which may reduce the off current and may reduce current leakage in the subset of the transistors. The reduced off current and reduced current leakage may increase data retention in the subset of the transistors and/or may increase the reliability of the subset of the transistors without increasing the footprint of the subset of the transistors. Moreover, the particular shape of the channel layer enables the subset of the transistors to be formed with a top-gate structure, which provides low integration complexity with other transistors in the capacitorless DRAM cell.

  • Publication number: 20230153505
    Abstract: Electronic design automation (EDA) of the present disclosure logically places components of the electronic circuitry onto an electronic design real estate to determine an architectural design placement for the electronic circuitry. The EDA evaluates a metaheuristic algorithm starting with an initial placement of components of the electronic circuitry onto the electronic design real estate to provide multiple possible placements for placing these components of the electronic circuitry onto the electronic design real estate. The EDA utilizes the multiple possible placements of the metaheuristic algorithm to train one or more probabilistic functions of a model-based reinforcement learning (RL) algorithm. The EDA evaluates the model-based RL algorithm utilizing the one or more probabilistic functions to determine the architectural design placement.
