  • Patent number: 11923035
    Abstract: A pseudo dual port memory device in which an operating speed is improved and stability is increased is provided. The pseudo dual port memory device may include a memory cell, a pair of bit lines connected to the memory cell, a write driver, a sense amp, and a column multiplexer which is connected to the bit lines, receives a write multiplexer control signal and a read multiplexer control signal, connects the bit lines to the write driver in response to the write multiplexer control signal, and connects the bit lines to the sense amp in response to the read multiplexer control signal. A precharge control signal generation circuit which is connected to the column multiplexer may generate a precharge control signal on the basis of the read and write multiplexer control signals, and a bit line precharge circuit may precharge the bit lines based on the precharge control signal.

  • Publication number: 20240014160
    Abstract: A semiconductor package includes a substrate having opposite first and second surfaces; (1-1)-th substrate pads and (1-2)-th substrate pads on the first surface of the substrate; first connecting terminals on the (1-1)-th substrate pads and the (1-2)-th substrate pads; (2-1)-th substrate pads and (2-2)-th substrate pads on the second surface of the substrate; an interposer on the second surface of the substrate; second connecting terminals between the (2-1)-th substrate pads, the (2-2)-th substrate pads, and the interposer; and a first semiconductor chip on the interposer. The (1-2)-th substrate pads have a smaller maximum width than the (1-1)-th substrate pads. The (2-2)-th substrate pads have a smaller maximum width than the (2-1)-th substrate pads. The (1-1)-th substrate pads and the (2-1)-th substrate pads transmit first signals, ground signals, or power signals. The (1-2)-th substrate pads and the (2-2)-th substrate pads transmit second signals that are faster than the first signals.
