Publication number: 20240126692Abstract: Memory devices and systems with post-packaging master die selection, and associated methods, are disclosed herein. In one embodiment, a memory device includes a plurality of memory dies. Each memory die of the plurality includes a command/address decoder. The command/address decoders are configured to receive command and address signals from external contacts of the memory device. The command/address decoders are also configured, when enabled, to decode the command and address signals and transmit the decoded command and address signals to every other memory die of the plurality. Each memory die further includes circuitry configured to enable, or disable, or both individual command/address decoders of the plurality of memory dies. In some embodiments, the circuitry can enable a command/address decoder of a memory die of the plurality after the plurality of memory dies are packaged into a memory device.Type: ApplicationFiled: December 26, 2023Publication date: April 18, 2024Inventors: Evan C. Pearson, John H. Gentry, Michael J. Scott, Greg S. Gatlin, Lael H. Matthews, Anthony M. Geidl, Michael Roth, Markus H. Geiger, Dale H. Hiscock

Publication number: 20200180233Abstract: An inventive composition and process for formation of a conductive bonding film are disclosed. The invention combines adhesive bonding sheet technologies (e.g. die attach films, or DAFs) with the electrical and thermal conductivity performance of transient liquid phase sintered paste compositions. The invention films are characterized by high bulk thermal and electrical conductivity within the film as well as low and stable thermal and electrical resistance at the interfaces between the inventive film and metallized adherends.Type: ApplicationFiled: February 14, 2020Publication date: June 11, 2020Inventors: Catherine A. SHEARER, Peter A. MATTURRI, Michael C. MATTHEWS

Patent number: 9583453Abstract: Sintering die-attach materials provide a lead-free solution for semiconductor packages with superior electrical, thermal and mechanical performance to prior art alternatives. Wafer-applied sintering materials form a metallurgical bond to both semiconductor die and adherends as well as throughout the die-attach joint and do not remelt at the original process temperature. Application to either one or both sides of the wafer, as well as paste a film application are disclosed.Type: GrantFiled: May 30, 2013Date of Patent: February 28, 2017Assignee: Ormet Circuits, Inc.Inventors: Catherine Shearer, Michael C Matthews, Peter A Matturi, Eunsook Barber, Richard Weaver

Patent number: 8221518Abstract: The present invention provides electrically and thermally conductive compositions for forming interconnections between electronic elements. Invention compositions comprise three or more metal or metal alloy particle types and an organic vehicle comprising a flux that is application specific. The first particle type includes a reactive high melting point metal that reacts with a reactive low melting point metal(s) in the other particles to form intermetallic species. The reactive low melting point metal(s) of the invention are provided in two distinct particle forms. The first reactive low melting point metal particle includes a carrier that facilitates the reaction with the reactive high melting point metal. The second reactive low melting point metal particle acts primarily as a source of the reactive low melting point metal.Type: GrantFiled: March 31, 2010Date of Patent: July 17, 2012Assignee: Ormet Circuits, Inc.Inventors: Catherine Shearer, Kenneth C. Holcomb, G. Delbert Friesen, Michael C. Matthews
