Embodiment
Please refer to Fig. 2, first embodiment of the invention shown in it has the pick-up unit and the external device (ED) of measuring ability.Pick-up unit comprises on the control chip 230, and draws element (for example resistance R), a socket 200 and a detection chip 260.Insert SATA interface socket 200 in order to want to detect memory storage in real time, the present invention is by optional one, for example article one grounding conductance line in the defined three grounding conductance lines of SATA interface.Afterwards, article one grounding conductance line in the SATA interface socket 200 is drawn element (pull up device) on one, for example a pull-up resistor (pull up register, R), be connected to a supply voltage (Vcc), and this article one grounding conductance line can be considered a detection pin position (DET).
Moreover the annexation of other electrical lead on the SATA interface socket 200 does not change.That is to say, control chip 230, for example two the transmission ends pin positions (Tx) on the South Bridge chip, two receiving end pin positions (Rx) be connected to respectively SATA interface socket 200 second and third, five, six electrical leads.Moreover the 4th, seven electrical leads of SATA interface socket 100 then are connected directly to the ground plane (ground layer) on the motherboard.
According to the first embodiment of the present invention, on motherboard, can utilize the input and output pin position (I/O pin) of a detection chip 260 to be connected to this detection pin position (DET), make this detection chip 260 to learn whether memory storage 240 has the SATA of insertion interface socket 200 according to the signal that detects on the pin position (DET).Moreover, this detection chip 260 can be a super input-output unit (Super I/O device) on the motherboard or universal input-output unit (general purpose I/P, GPIO) or South Bridge chip.
Clearly, when memory storage 240 did not insert SATA interface socket 200, (pull up) can be drawn high to high level in the detection pin position (DET) of SATA interface socket 200; Otherwise, when memory storage 240 inserts SATA interface socket 200,, first of SATA interface plug 220 is connected to ground voltage owing to connecing the grounding conductance line, and therefore, the detection pin position (DET) of SATA interface socket 200 can be dragged down (pull down) to low level.And detection chip 260 can determine that in low level this memory storage 240 has inserted SATA interface socket 200 according to detecting pin position (DET), and the notice computer system.
As shown in the above description, when memory storage 240 inserts SATA interface socket 200,, therefore meet the definition of SATA interface because the first grounding conductance line of SATA interface plug 220 and SATA interface socket 200 is connected to ground voltage.Though when memory storage 240 did not insert SATA interface socket 200, SATA interface socket 200 did not also meet the definition of SATA interface and since without any memory storage connect, therefore can't have problems.
Please refer to Fig. 3, it is depicted as pick-up unit and external device (ED) that second embodiment of the invention has measuring ability.Compared to first example, second embodiment provides an electronic type electronic switch (switch) 235 to be connected in and detects between pin position (DET) and the ground voltage, and a control end of electronic type electronic switch 235 also is connected to detection pin position (DET).The similar switch of the operating principle of this electronic type electronic switch 235, and this switch can move according to the level that detects on the pin position (DET).When detection pin position (DET) was low level, this electronic switch 235 was a closed condition (close state), will detect pin position (DET) and be connected to ground voltage; Otherwise when detection pin position (DET) was high level, this electronic switch 235 was to open state (open state), can not be connected to ground voltage with detecting pin position (DET).
Clearly, when memory storage 240 inserts SATA interface socket 200, detecting pin position (DET) is low level, therefore, the electric current (I) that is produced through pull-up resistor (R) by voltage source (Vcc) no longer connects the grounding conductance line through first of SATA interface socket 200 and is passed to memory storage 240, but is passed to ground voltage via electronic type electronic switch 235.Therefore, the second embodiment of the present invention is except the specification that meets the SATA interface, and the data that also can not influence the SATA interface transmit and inbound pacing.
In sum; though the present invention discloses as above with preferred embodiment; yet it is not in order to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; when can doing various changes and modification, so protection scope of the present invention is as the criterion when looking the scope that claim defines.
