  • Patent number: 7757061
    Abstract: A system and method for decoding command signals that includes a command decoder configured to generate internal control signals to perform an operation based on the command signals and an operating state. The same combination of command signals can request different commands depending on the operating state. A command is selected from a first set of operations according to the command signals when the memory system is in a first operating state and a command is selected from a second set of operations according to the command signals when the memory system is in a second operating state.

  • Publication number: 20100142251
    Abstract: Techniques are disclosed for reading operating parameters from programmable elements on memory devices to configure a memory system. More specifically, programmable elements, such as antifuses, located on a memory device are programmed during fabrication with measured operating parameters corresponding to the memory device. Operating parameters may include, for example, operating current values, operating voltages, or timing parameters. The memory device may be incorporated into a memory module that is incorporated into a system. Once the memory module is incorporated into a system, the programmable elements may be accessed such that the memory system can be configured to optimally operate in accordance with the operating parameters measured for each memory device in the system.

  • Publication number: 20090283898
    Abstract: Pass-through 3D interconnects and microelectronic dies and systems of stacked dies that include such interconnects to disable electrical connections are disclosed herein. In one embodiment, a system of stacked dies includes a first microelectronic die having a backside, an interconnect extending through the first die to the backside, an integrated circuit electrically coupled to the interconnect, and a first electrostatic discharge (ESD) device electrically isolated from the interconnect. A second microelectronic die has a front side coupled to the backside of the first die, a metal contact at the front side electrically coupled to the interconnect, and a second ESD device electrically coupled to the metal contact. In another embodiment, the first die further includes a substrate carrying the integrated circuit and the first ESD device, and the interconnect is positioned in the substrate to disable an electrical connection between the first ESD device and the interconnect.

  • Patent number: 7590797
    Abstract: An apparatus and method couples memory devices in a memory module to a memory hub on the module such that signals traveling from the hub to the devices have approximately the same propagation time regardless of which device is involved. Specifically, the devices are arranged around the hub in pairs, with each pair of devices being oriented such that a functional group of signals for each device in the pair, such as the data bus signals, are positioned adjacent each other on a circuit board of the module. This allows for a data and control-address busses having approximately the same electrical characteristics to be routed between the hub and each of the devices. This physical arrangement of devices allows high speed operation of the module. In one example, the hub is located in the center of the module and eight devices, four pairs, are positioned around the hub.
