Embodiment
Particular content of the present invention is described as follows.At first please refer to the system block diagrams of Fig. 1.Figure 1 shows that design of electronic circuits calcspar of the present invention, wherein 100 is mini PCIe interface, and 110 is a host bus converter, and it is built-in with a flash memory Memory Controller Hub 112 and power circuit 114,110 connect an internal memory signal coupling arrangement 120, and it is connected with memory subassembly array 130.Mini PCIe interface 100 wherein forms a printed circuit board (PCB) and becomes support plate (Carrier Board) with host bus converter 100 layouts, and memory subassembly array 130 independent layouts form another printed circuit board (PCB) and become storing template (Memory Board), between support plate and the storing template, see through internal memory signal coupling arrangement 120 circuits and be connected, and form a complete solid magnetic disc circuit both.
Refer again to Fig. 2, shown in Figure 200, be the design of mini PCIe interface solid disk module product of the present invention, comprising support plate 210, storing template 220, mini PCIe interface 211, internal memory signal coupling arrangement 300 and storing template ridge 221, this ridge is formed by printed circuit board (PCB), its objective is to form hatch frame 222 in the both sides of printed circuit board (PCB) one end, combine with screw hole 212 on the support plate 210 by hatch frame 222 solid magnetic disc module 200 is locked on the mainboard (Main Board) of system admittedly and be beneficial to outside screw.And utilize this ridge 221, can be on it with internal memory signal coupling arrangement 300 layouts, making full use of space limited on the printed circuit board (PCB), and memory subassembly will be placed in most of space on the storing template 220, to design maximum memory density solid magnetic disc product.Because if internal memory signal coupling arrangement 300 is placed in other place of storing template 220, will form unnecessary mechanism because of the intrinsic encapsulation of flash memory storage chip (Package) structure interferes, and must give up part flash memory storage chip, therefore can't reach the highest chip layout quantity, greatly reduce memory capacity.Unless the printed circuit board sizes that strengthens storing template 220 is including enough flash memory storage chips in, but this will go beyond the code requirement of mini PCIe standard to the device length and width again, rather than a preferable solution.Therefore the present invention on ridge 221, is the method for designing an of the best with internal memory signal coupling arrangement 300 layouts in fact.
Utilize the mini PCIe solid magnetic disc modular design of separate type of the present invention, not only can reach maximum memory size, also storing template 220 designs because have independently when production test, therefore can independently finish at storing template 220 dispatching from the factory of memory chip tested and planned suitable memory information, for example: downright bad block management (Bad BlockManagement).And this time that will take the overwhelming majority to the storage chip sweep test, and the test duration also will increase along with the increase of memory capacity, therefore with master controller support plate 210 discrete testings, just can carry out the testing process planning of Multi-Tasking to solid magnetic disc, and improve the integral production tested performance of solid magnetic disc.Especially bad, PCIe multichip system integrated scheme for present majority, it must use a PCIe bridging chip, see through the IDE/SATA signal, the internal memory control chip of arranging in pairs or groups is finished control circuit, and this mode often need be on solid magnetic disc the internal memory production test work when producing of the extra IDE of layout or SATA interlock circuit to cooperate, yet after production test finishes, the circuit of this part is just idle useless, forms the waste of resource.And separate type design of the present invention only needs IDE or SATA relevant circuit layout just can be carried out production test to storing template 220 on the production test tool, has significantly reduced the control circuit complexity and the Material Cost of solid magnetic disc.
And in stock control, adopt mode of the present invention, can separate manufacturing and both are done different safety inventory management at different clients' demand support plate and storing template, significantly reduced the pressure of production firm to the memory subassembly stock of Price Sensitive, this is the designs fix because of support plate, the difference because of memory capacity does not need different designs, therefore as long as arrange in pairs or groups suitable storing template, but just production shipment.Also because the versatility of support plate is big, in the past at the product of different capabilities, for example: 256MB, 512MB, 1GB, 2GB, 4GB, 8GB, 16GB, 32GB, 64GB etc., each needs under the safety inventory situation of certain amount, stock's fund is high, must prepare too late production delivery risk in the face of former material again if downgrade the stock.And the product that utilizes separate type of the present invention to design, only need support plate is done a spot of stock control, though storing template is still kept identical stock's amount, so its cost declines to a great extent because of not containing support plate circuit units such as controller chip, the therefore whole overstocked amount of stores fund that reduced.
On the other hand, for the small-sized scale manufacturing merchant who is reluctant to bear internal memory stock loss from falling price, the risk pressure that order is before just got the raw materials ready and produced, also because of the low loss from falling price characteristic of support plate, make small-sized manufacturer can begin low-risk support plate is carried out separately the management of safety inventory, improve the compliance rate of deliver the goods, and reduced the risk of whole former material buying and production transaction.
To sum up institute is old, and no matter the present invention is showing it totally different in prior art feature with regard to purpose, means and effect, and it is at first invented and is suitable for practicality, also meets the patent requirement of invention, earnestly asks your juror and perceives, and pray and vouchsafe patent early, in order to do Jiahui society, the true feeling moral is just.
