  • Publication number: 20250118355
    Abstract: A signal receiver includes a data receiver and a data strobe signal receiver. The data receiver includes a plurality of current mode logic circuits and a plurality of data latches. A first stage current mode logic circuit receives a data signal, and a final stage current mode logic circuit outputs an amplified data signal. The plurality of data latches receive the amplified data signal, wherein each of the data latches sums the amplified data signal and a plurality of feedback data to obtain a summing data, and latches the summing data to output an output data according to one of a plurality of amplified data strobe signals. The data strobe signal receiver receives a data strobe signal, and generates the plurality of amplified data strobe signals by dividing a frequency of the data strobe signal.

  • Patent number: 9886071
    Abstract: A memory storage device having a rewritable non-volatile memory module, a first connection interface unit, a second connection interface unit, a power management circuit and a memory control circuit unit is provided. When an external power supply device is electrically connected to the second connection interface unit, the power management circuit receives a second power supply voltage from the external power supply device via the second connection interface unit, supplies an operation voltage to the rewritable non-volatile memory module and the memory control circuit unit and supplies the second power supply voltage to a host device. When the external power supply device is electrically disconnected with the second connection interface unit, the power management circuit receives a first power supply voltage from the host device via the first connection interface unit and supplies the operation voltage to the memory control circuit unit and the rewritable non-volatile memory module.

  • Patent number: 8395869
    Abstract: ESD protection circuit with EOS immunity is provided, which includes a first connection circuit, a first EOS control circuit formed by at least a diode, and an ESD clamp respectively coupled between a pad, a first clamp node, an I/O clamp node and a second source node. When the ESD clamp detects ESD through the I/O clamp node, it is triggered to conduct from the I/O clamp node to the second source node. When the pad receives EOS, the first EOS control circuit provides a cross voltage between the first clamp node and the I/O clamp node, such that a voltage of the I/O clamp node becomes less than a characteristic voltage of the ESD clamp to prevent the ESD clamp from reverse conducting.

  • Patent number: 7170800
    Abstract: A low-power delay buffer circuit is provided, which utilizes a ring counter as address decoder and a latch array for memory. To reduce power consumption, a gated-clock driver tree is applied to the ring-counter addressing architecture. Moreover, a similar gated-driver tree is applied to the input and output ports of the latch array. The delay buffer circuit not only could achieve a power consumption lower than SRAM-based delay buffers, but also could operation under high frequencies and take up less layout area than SRAM-based delay buffers.
