  • Patent number: 11955154
    Abstract: A sense amplifier circuit includes a sense amplifier, a switch and a temperature compensation circuit. The temperature compensation circuit provides a control signal having a positive temperature coefficient, based on which the switch provides reference impedance for temperature compensation. The sense amplifier includes a first input end coupled to a target bit and a second input end coupled to the switch. The sense amplifier outputs a sense amplifier signal based on the reference impedance and the impedance of the target bit.

  • Patent number: 11935871
    Abstract: A semiconductor package including a first semiconductor die, a second semiconductor die, a first insulating encapsulation, a dielectric layer structure, a conductor structure and a second insulating encapsulation is provided. The first semiconductor die includes a first semiconductor substrate and a through silicon via (TSV) extending from a first side to a second side of the semiconductor substrate. The second semiconductor die is disposed on the first side of the semiconductor substrate. The first insulating encapsulation on the second semiconductor die encapsulates the first semiconductor die. A terminal of the TSV is coplanar with a surface of the first insulating encapsulation. The dielectric layer structure covers the first semiconductor die and the first insulating encapsulation. The conductor structure extends through the dielectric layer structure and contacts with the through silicon via.
