  • Patent number: 11894370
    Abstract: Methods of cutting gate structures and fins, and structures formed thereby, are described. In an embodiment, a substrate includes first and second fins and an isolation region. The first and second fins extend longitudinally parallel, with the isolation region disposed therebetween. A gate structure includes a conformal gate dielectric over the first fin and a gate electrode over the conformal gate dielectric. A first insulating fill structure abuts the gate structure and extends vertically from a level of an upper surface of the gate structure to at least a surface of the isolation region. No portion of the conformal gate dielectric extends vertically between the first insulating fill structure and the gate electrode. A second insulating fill structure abuts the first insulating fill structure and an end sidewall of the second fin. The first insulating fill structure is disposed laterally between the gate structure and the second insulating fill structure.

  • Publication number: 20240028103
    Abstract: Systems, apparatuses, and methods for saving power on a bus interface are described. A system includes a host, a device, and a repeater interposed between the host and the device. While the host and device are in a low-power state, the repeater monitors a first bus to determine if the device has woken up. When the repeater detects a remote wake-up event initiated by the device, the repeater generates an interrupt which is sent to the host. The host responds to the interrupt by initiating a resume wake-up event procedure that assumes the device is still asleep. In this way, the host is able to stay in the low-power state longer while also using a wake-up procedure that does not require the host to be aware of the existence of the repeater.

  • Patent number: 11829242
    Abstract: Techniques are disclosed relating to improving memory reliability, e.g., in the context of memory circuits with limited reliability features. In some embodiments, memory controller circuitry is configured to communicate with memory circuitry via an interface that supports link error detection. The memory controller circuitry may, based on a corruption indicator, transmit a data and parity combination for the first data block that causes the memory circuitry to detect an uncorrectable write interface error. Subsequent reads of the location may therefore cause an uncorrectable error indication. This may advantageously allow the memory controller circuitry to propagate a corruption indicator as an uncorrectable error in the memory circuit, without requiring additional tracking of the indicator by the memory circuit or memory controller, in some embodiments.

  • Patent number: 11809847
    Abstract: One or more computer processors identify a string within source code associated with a program integrated interface (PII). The one or more computer processors compare the identified string to a string entry comprised in a PII dictionary. The one or more computer processors, responsive to a match between the identified string and the string entry in the PII dictionary, classify the identified string as translatable or non-translatable based on a classification associated with the string entry. The one or more computer processors, responsive to a non-match between the identified string and the string entry in the PII dictionary, classify the identified string as translatable or non-translatable utilizing a hyperplane model trained with a margin (C) derived from unlimited search. The one or more computer processors, responsive to a classified translatable string, translate the classified translatable string.

  • Publication number: 20230325274
    Abstract: Techniques are disclosed relating to improving memory reliability. In some embodiments, memory circuitry includes memory cells configured to store data, interface circuitry, and on-die error correcting code (ECC) circuitry. The ECC circuitry may check read data from the memory cells for errors and correct detected correctable errors to generate corrected data. The memory circuitry may provide read data to a requesting circuit via the interface circuitry, including one or more sets of corrected data from the on-die ECC circuitry. The memory circuitry may provide a decoding status flag (DSF) via the interface circuitry, including to: set the DSF to a first value in response to no error being detected for a given set of provided read data, set the DSF to a second value in response to a correctable error that was detected and corrected by the on-die ECC circuitry to provide a given set of read data, and set the DSF to a third value in response to an uncorrectable error detected by the on-die ECC circuitry.

  • Publication number: 20230325344
    Abstract: An apparatus includes components, a distributed timebase circuit, an interface and a Time Synchronization Circuit (TSC). The timebase circuit is configured to provide local timebases in physical proximity to the components, and synchronize the local timebases to a global timebase so as to provide a consistent time measurement. The interface is configured to be coupled to one or more devices. Transmissions on the interface are logically divided into a plurality of frames. Time on the interface is defined based on a frame number identifying a particular frame. The TSC is configured to capture a first timestamp based on the frame number corresponding to a point in time on the interface, and to concurrently capture a second timestamp based on a local timebase corresponding to the point in time, wherein the first timestamp and the second timestamp correlate time on the interface to the consistent time measurement.

  • Publication number: 20230253263
    Abstract: An anchored cut-metal gate (CMG) plug, a semiconductor device including the anchored CMG plug and methods of forming the semiconductor device are disclosed herein. The method includes performing a series of etching processes to form a trench through a metal gate electrode, through an isolation region, and into a semiconductor substrate. The trench cuts-through and separates the metal gate electrode into a first metal gate and a second metal gate and forms a recess in the semiconductor substrate. Once the trench has been formed, a dielectric plug material is deposited into the trench to form a CMG plug that is anchored within the recess of the semiconductor substrate and separates the first and second metal gates. As such, the anchored CMG plug provides high levels of resistance to reduce leakage current within the semiconductor device during operation and allowing for improved V-trigger performance of the semiconductor device.
