Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further and to be specified.
Fig. 1 is the structural representation of the utility model based on the portable high-speed solid-state memory of USB technology.
Embodiment
As shown in Figure 1, the portable high-speed solid-state memory mainly is made up of housing 8, PCIe interface 1, host-USB3.0 interface 2, device-USB3.0 interface 3, PCIe-USB3.0 signaling conversion circuit 4, high speed signal gating circuit 5, solid state storage circuit.Housing 8 adopts Express card/34 standard, and integral body is flat rectangular parallelepiped, and housing 8 one ends are provided with thickness obviously greater than the link of housing 8 remainder thickness, and the xsect of this link is trapezoidal.PCIe interface 1, host-USB3.0 interface 2, device-USB3.0 interface 3, PCIe-USB3.0 signaling conversion circuit 4, high speed signal gating circuit 5, solid state storage circuit all are positioned at housing 8 inside.PCIe interface 1, host-USB3.0 interface 2, high speed signal gating circuit 5 all are connected with PCIe-USB3.0 signaling conversion circuit 4, and device-USB3.0 interface 3, solid state storage circuit all are connected with high speed signal gating circuit 5.Host-USB3.0 interface 2, device-USB3.0 interface 3 are arranged on the link place of housing 8, and PCIe interface 1 is arranged on the other end of housing 8.Solid state storage circuit comprises solid-state hard disk SSD 6 and USB3.0-SATA signaling conversion circuit 7, and solid-state hard disk SSD 6 is connected with high speed signal gating circuit 5 through USB3.0-SATA signaling conversion circuit 7.
When the portable high-speed solid-state memory is used as common movable storage device, can reach the function of IO interface through using device-USB3.0 interface 3, device-USB3.0 interface 3 has all characteristics of USB3.0 interface.With after peripherals is connected, high speed signal gating circuit 5 monitors device-USB3.0 interface 3 and just is being used through device-USB3.0 interface 3, and this moment, 5 of high speed signal gating circuits allowed device-USB3.0 interface 3 visit solid state storage circuits.When writing data; Input to USB3.0-SATA signaling conversion circuit 7 from the signal of device-USB3.0 interface 3 inputs through high speed signal gating circuit 5; This USB3.0-SATA signaling conversion circuit 7 can become the conversion of signals that meets the USB3.0 technical standard SATA signal of serial hardware driver interface use, also can the SATA conversion of signals that serial hardware driver interface uses be become meet the signal of USB3.0 technical standard.Thus, signal converts solid-state hard disk SSD 6 default signal to and stores 6 li of solid-state hard disk SSD into through USB3.0-SATA signaling conversion circuit 7.When sense data, the data-switching that USB3.0-SATA signaling conversion circuit 7 will be stored in solid-state hard disk SSD 6 becomes to meet the signal of USB3.0 technical standard, signal through 5 outputs of high speed signal gating circuit at device-USB3.0 interface 3.Just become jumbo high speed storing mobile device through said process portable high-speed solid-state memory; Have bigger memory capacity and data transmission capabilities faster than USB flash disk of the prior art; Also has data transmission capabilities faster than hard disk of the prior art; Its speed that writes data can reach 80MB/S, and the speed of reading of data can reach 110MB/S.
