摘要： A virtual force controlled collapse chip connection (C4) pad placement optimization frame-work for 2D power delivery grids is proposed. The present optimization framework regards power pads as mobile “positive charged particles” and current resources as a “negative charged back-ground.” The virtual electrostatic force is calculated from voltage gradients. This optimization framework optimizes pad locations by moving pads according to the virtual forces exerted on them by other pads and current sources in the system. Within this framework, three algorithms are proposed to meet various requirements of optimization quality and speed. These algorithms minimize resistive voltage drop (IR drop), the maximum current density, and power distribution network metal power dissipation at the same time.

摘要： The present invention proposes an electronic memory device comprising a memory line including a memory domain. The memory line may contain a number of memory domains and a number of fixed domains, wherein each memory domain stores a single binary bit value. A multiferroic element may be disposed proximate to each memory domain allowing the magnetization of the memory domain to be changed using a spin torque current, and ensuring the stability of the magnetization of the domain when it is not being written. The domain boundary between the memory domain and one of its adjacent fixed domains may thereby be moved. An antiferromagnetic element may be disposed proximate to each fixed domain to ensure the stability of the magnetization of these. The value of each memory domain may be read by applying a voltage to a magnetic tunnel junction comprising the memory domain and measuring the current flowing through it.

摘要： Embodiments circuits provide a transistor body bias voltage so that the ratio of ION to IOFF is constant over a range of temperature, where ION is a transistor current when ON and IOFF is a (leakage) transistor current when OFF. In one embodiment, a nFET is biased to provide ION to a current mirror that sources a current AION to a node, a nFET is biased to provide IOFF to a current mirror that sinks a current BIOFF from the node, and an amplifier provides feedback from the node to the body terminals of the nFETs so that at steady state AION=BIOFF, where A and B are constants independent over a range of temperature. In this way, the ratio ION/IOFF is maintained at B/A for some range of temperatures. Other embodiments are described and claimed.

摘要： A system of individually adjusting noise immunity of each input of a dynamic circuit including parallel or series-parallel pull-down network comprises identifying precharge nodes of the dynamic circuit requiring a reduction of noise. Then further identifying NMOS transistor drains connected to the respective precharge nodes, then creating a pull-up network of PMOS transistors for the precharge nodes, respectively. After creating a pull-up network of PMOS transistors, the system further includes arranging the order of the PMOS transistors corresponding to the respective precharge nodes to improve the noise immunity and performance of the dynamic circuit. After completing the arranging of the order of the PMOS transistors, the system can further include sizing the PMOS transistors to achieve the required reduction of noise for the precharge nodes, respectively.
