  • Patent number: 11823906
    Abstract: Direct-bonded native interconnects and active base dies are provided. In a microelectronic architecture, active dies or chiplets connect to an active base die via their core-level conductors. These native interconnects provide short data paths, which forgo the overhead of standard interfaces. The system saves redistribution routing as the native interconnects couple in place. The base die may contain custom logic, allowing the attached dies to provide stock functions. The architecture can connect diverse interconnect types and chiplets from various process nodes, operating at different voltages. The base die may have state elements for drive. Functional blocks aboard the base die receive native signals from diverse chiplets, and communicate with all attached chiplets. The chiplets may share processing and memory resources of the base die. Routing blockages are minimal, improving signal quality and timing. The system can operate at dual or quad data rates.

  • Patent number: 11688776
    Abstract: A microelectronic unit may include an epitaxial silicon layer having a source and a drain, a buried oxide layer beneath the epitaxial silicon layer, an ohmic contact extending through the buried oxide layer, a dielectric layer beneath the buried oxide layer, and a conductive element extending through the dielectric layer. The source and the drain may be doped portions of the epitaxial silicon layer. The ohmic contact may be coupled to a lower surface of one of the source or the drain. The conductive element may be coupled to a lower surface of the ohmic contact. A portion of the conductive element may be exposed at the second dielectric surface of the dielectric layer. The second dielectric surface may be directly bonded to an external component to form a microelectronic assembly.

  • Patent number: 11398258
    Abstract: A module for multiple dies is disclosed. The module can include a group of dies that include a first die having a first voltage block and a second die having a second voltage block. The module can also include an interconnect that electrically connects the first and second dies. Power supply generation in the first die is enabled in non-active mode, while power supply generation in the second die is disabled. The power supply generation in the second die may be enabled when the second die is in active mode. The first die can send enabling signal to the second the die to enable the second die. The first die can provide supply to the second die in the non-active mode. The first die can send self-refresh timing command to the second die when the module is in a self-refresh mode.

  • Publication number: 20220020741
    Abstract: A microelectronic circuit structure comprises a stack of bonded layers comprising a bottom layer and at least one upper layer. At least one of the upper layers comprises an oxide layer having a back surface and a front surface closer to the bottom layer than the back surface, and a plurality of FD-SOI transistors built on the from surface. At least a first back gate line and a second back gate line extend separate from each other above the back surface for independently providing a first back gate bias to a first group of transistors and a second back gate bias to a second different group of transistors.

  • Publication number: 20210118864
    Abstract: The present disclosure provides for a stacked memory combining RAM and one or more layers of NVM, such as NAND. For example, a first layer of RAM, such as DRAM, is coupled to multiple consecutive layers of NAND using direct bonding interconnect (DBI®). Serialization and overhead that exists in periphery of the NVM may be stripped to manage the data stored therein. The resulting connections between the RAM and the NVM are high bandwidth, high pincount interconnects. Interconnects between each of the one or more layers of NVM are also very dense.

  • Patent number: 10684929
    Abstract: This disclosure pertains to hardware compute arrays (sometimes called systolic arrays) for applications such as artificial intelligence (AI), machine learning (ML), digital signal processing (DSP), graphics processing units (GPUs), and other computationally intensive applications. More particularly, it pertains to novel and advantageous architecture innovations for efficiently and inexpensively implementing such arrays using multiple integrated circuits. Hardware and methods are disclosed to allow compute arrays to be tested after face-to-face or wafer-to-wafer bonding and without out any pre-bonding test. Defects discovered in the post-bonding testing can be completely or partially healed increasing yields and reducing costs.
