  • Publication number: 20240079557
    Abstract: An anode active material for a secondary battery according to an embodiment of the present application includes lithium-silicon composite oxide particle. The lithium-silicon composite oxide particles include at least one selected from the group consisting of Li2SiO3 and Li2Si2O5 and have a phase fraction ratio defined by Equation 1 of 1.0 or less. A content of particles having a diameter of less than 3 ?m is 5 vol % or less based on a total volume of the lithium-silicon composite oxide particles.

  • Patent number: 10078358
    Abstract: A power delivery network (PDN) including a battery, a set of regulators for generating supply voltages, and an integrated circuit (IC) including power rails configured to receive the supply voltages. The IC further includes an IC chip having a set of cores. The power rails includes a larger rail configured to provide a full range of currents, and the other smaller power rails each configured to provide lower range of currents. The IC includes multiplexers having first inputs coupled respectively to the smaller rails, second inputs coupled to the larger rail, and outputs coupled to the cores. When the smaller rail is able to supply the current needed by a core, the multiplexer is configured to couple the smaller rail to the core. When the smaller rail cannot supply the current needed by the core, the multiplexer is configured to couple the larger rail to the core.

  • Patent number: 9620452
    Abstract: An apparatus including a conductive stack structure includes an Mx layer interconnect on an Mx layer and extending in a first direction on a first track, an My layer interconnect on an My layer in which the My layer is a lower layer than the Mx layer, a first via stack coupled between the Mx layer interconnect and the My layer interconnect, a second via stack coupled between the Mx layer interconnect and the My layer interconnect, a second Mx layer interconnect extending in the first direction on a track immediately adjacent to the first track, and a third Mx layer interconnect extending in the first direction on a track immediately adjacent to the first track. The Mx layer interconnect is between the second Mx layer interconnect and the third Mx layer interconnect. The second Mx layer interconnect and the third Mx layer interconnect are uncoupled to each other.
