Patent number: 12199068Abstract: Disclosed is a microelectronic device assembly comprising a substrate having conductors exposed on a surface thereof. Two or more microelectronic devices are stacked on the substrate, each microelectronic device comprising an active surface having bond pads operably coupled to conductive traces extending over a dielectric material to via locations beyond at least one side of the stack, and vias extending through the dielectric materials at the via locations and comprising conductive material in contact with at least some of the conductive traces of each of the two or more electronic devices and extending to exposed conductors of the substrate. Methods of fabrication and related electronic systems are also disclosed.Type: GrantFiled: August 5, 2022Date of Patent: January 14, 2025Assignee: Micron Technology, Inc.Inventors: Owen R.

Patent number: 12176061Abstract: Described apparatuses and methods enable communication between a host device and a memory device to establish relative delays between different data lines. If data signals propagate along a bus with the same timing, simultaneous switching output (SSO) and crosstalk can adversely impact channel timing budget parameters. An example system includes an interconnect having multiple data lines that couple the host device to the memory device. In example operations, the host device can transmit to the memory device a command indicative of a phase offset between two or more data lines of the multiple data lines. The memory device can implement the command by transmitting or receiving signals via the interconnect with different relative phase offsets between data lines. The host device (e.g., a memory controller) can determine appropriate offsets for a given apparatus. Lengths of the offsets can vary. Further, a system can activate the phase offsets based on frequency.Type: GrantFiled: January 23, 2024Date of Patent: December 24, 2024Assignee: Micron Technology, Inc.Inventors: Kang-Yong Kim, Hyun Yoo Lee, Timothy M.

Patent number: 12148711Abstract: Semiconductor devices with antennas and electromagnetic interference (EMI) shielding, and associated systems and methods, are described herein. In one embodiment, a semiconductor device includes a semiconductor die coupled to a package substrate. An antenna structure is disposed over and/or adjacent the semiconductor die. An electromagnetic interference (EMI) shield is disposed between the semiconductor die and the antenna structure to shield at least the semiconductor die from electromagnetic radiation generated by the antenna structure and/or to shield the antenna structure from interference generated by the semiconductor die. A first dielectric material and/or a thermal interface material can be positioned between the semiconductor die and the EMI shield, and a second dielectric material can be positioned between the EMI shield and the antenna structure.Type: GrantFiled: November 11, 2021Date of Patent: November 19, 2024Inventors: Owen R.

Publication number: 20240323062Abstract: Described apparatuses and methods are directed to equalization with pulse-amplitude modulation (PAM) signaling. As bus frequencies have increased, the time for correctly transitioning between voltage levels has decreased, which can lead to errors. Symbol decoding reliability can be improved with equalization, like with decision-feedback equalization (DFE). DFE, however, can be expensive for chip area and power usage. Therefore, instead of applying DFE to all voltage level determination paths in a receiver, DFE can be applied to a subset of such determination paths. With PAM4 signaling, for example, a DFE circuit can be coupled between an output and an input of a middle slicer. In some cases, symbol detection reliability can be maintained even with fewer DFE circuits by compressing a middle eye of the PAM4 signal. The other two eyes thus have additional headroom for expansion. Encoding schemes, impedance terminations, or reference voltage levels can be tailored accordingly.Type: ApplicationFiled: June 5, 2024Publication date: September 26, 2024Applicant: Micron Technology, Inc.Inventors: Kang-Yong Kim, Hyun Yoo Lee, Timothy M.
