  • Publication number: 20240143921
    Abstract: Techniques are described for training and/or utilizing sub-agent machine learning models to generate candidate dialog responses. In various implementations, a user-facing dialog agent (202, 302), or another component on its behalf, selects one of the candidate responses which is closest to user defined global priority objectives (318). Global priority objectives can include values (306) for a variety of dialog features such as emotion, confusion, objective-relatedness, personality, verbosity, etc. In various implementations, each machine learning model includes an encoder portion and a decoder portion. Each encoder portion and decoder portion can be a recurrent neural network (RNN) model, such as a RNN model that includes at least one memory layer, such as a long short-term memory (LSTM) layer.

  • Patent number: 11900996
    Abstract: Disclosed is a memory structure that includes wordlines (WL) and cell supply lines (CSL) positioned between and parallel to voltage boost lines (VBLs). The VBLs enable capacitive coupling-based voltage boosting of the adjacent WL and/or CSL depending on whether a read or write assist is required. During a read operation, all VBLs for a selected row can be charged to create coupling capacitances with the WL and with the CSL and thereby boost both the wordline voltage (Vwl) and the cell supply voltage (Vcs) for a read assist. During a write operation, one VBL adjacent to the WL for a selected row can be charged to create a coupling capacitance with the WL only and thereby boost the Vwl for a write assist. The coupling capacitances created by charging VBLs in the structure is self-adjusting in that as the length of the rows increase so do the potential coupling capacitances.

  • Patent number: 11769545
    Abstract: Disclosed are embodiments of a low-leakage row decoder and a memory circuit incorporating the row decoder. The row decoder includes wordline driver circuitry including first devices (pre-drivers) and second devices (wordline drivers). Each second device is connected in series between a first device and a wordline for a row in a memory array. The first devices can be directly connected to a positive supply voltage rail and connected to a ground rail through a footer. The second devices can be connected to the positive supply voltage rail through a header and directly connected to the ground rail. The on/off states of the header and footer are controlled by clock signal-dependent control signals so that they are either concurrently on or off. With this configuration, leakage power consumption of the wordline driver circuitry is minimized while the memory structures as idle and also while it operates in a normal active mode.

  • Patent number: 11495288
    Abstract: A disclosed sense circuit for a memory circuit includes sense amplifiers that detect differences in voltage levels on complementary bitlines during read operations. Instead of the sense amplifiers having built-in footer devices that lead to significant leakage, the sense circuit incorporates a common footer device for all sense amplifiers. To ensure that this footer device has sufficient drive strength to enable voltage differential detection by each sense amplifier, the sense circuit also includes a sense signal generation and boost circuit (SSG&B circuit) that generates a sense mode control signal (SEN) to control the on/off states of the footer device and that further boosts SEN, at the appropriate time, to increase the drive current. By using the common footer device and the SSG&B circuit, leakage from the sense circuit is reduced during a pre-charge operation mode without sacrificing performance during a read operation mode. Also disclosed are associated method embodiments.

  • Patent number: 11322200
    Abstract: A single-rail memory circuit includes an array of memory cells arranged in rows and columns and peripheral circuitry connected to the array for facilitating read and write operations with respect to selected memory cells. The peripheral circuitry includes, but is not limited to, boost circuits for the rows. Each boost circuit is connected to a wordline for a row and to a discrete voltage supply line for the same row. Each boost circuit for a row is configured to increase the voltage levels on the wordline and the voltage supply line for the row during a read of any selected memory cell within the row. Increasing the voltage levels on the wordline and on the voltage supply line during the read operation effectively boosts the read current. A method of operating the memory circuit reduces the probability of a read fail.
