    摘要: A magnetic tunnel junction (MTJ) device for a magnetic random access memory (MRAM) in a semiconductor back-end-of-line (BEOL) process flow includes a first metal interconnect for communicating with at least one control device and a first electrode for coupling to the first metal interconnect through a via formed in a dielectric passivation barrier using a first mask. The device also includes an MTJ stack for storing data coupled to the first electrode, a portion of the MTJ stack having lateral dimensions based upon a second mask. The portion defined by the second mask is over the contact via. A second electrode is coupled to the MTJ stack and also has a same lateral dimension as defined by the second mask. The first electrode and a portion of the MTJ stack are defined by a third mask. A second metal interconnect is coupled to the second electrode and at least one other control device.

    摘要: A semiconductor die including strain relief for through substrate vias (TSVs). The semiconductor die includes a semiconductor substrate having an active face. The semiconductor substrate includes conductive layers connected to the active face, The semiconductor die also includes a through substrate via extending only through the substrate. The through substrate via may include a substantially constant diameter through a length of the through substrate via. The through substrate via may be filled with a conductive filler material. The semiconductor die also includes an isolation layer surrounding the through substrate via. The isolation layer may include two portions: a recessed portion near the active face of the substrate capable of relieving stress from the conductive filler material, and a dielectric portion. A composition of the recessed portion may differ from the dielectric portion.

    摘要: A memory power management system and method supporting multiple power modes for powering memory channels. The power management system can include a memory controller that controls the memory channel; a throughput detector that detects a requested throughput of the memory channel; a power control logic that determines a desired power mode corresponding to the requested throughput; and a power control device that supplies a desired voltage of the desired power mode to the memory channel. The power management system can include multiple memory controllers for controlling a multi-channel memory independently. The method includes detecting a requested throughput for the memory channel; determining a desired voltage related to the requested throughput; requesting the desired voltage from a voltage device; and applying the desired voltage to the memory channel. In some embodiments, the method only applies the desired voltage if it does not change for a threshold time duration.

    摘要: A method to reduce electrostatic discharge susceptibility when assembling a stacked IC device. The method includes coupling a ground plane of a first semiconductor device and a ground plane of a second semiconductor device to substantially a same electrical potential. Active circuitry on the first semiconductor device and active circuitry on the second semiconductor device are electrically coupled after the ground planes are coupled. Electrically coupling the ground planes of the first and the second semiconductor device creates a preferred electrostatic discharge path to ground, thus minimizing potential damage to sensitive circuit elements.
