Abstract
The invention relates to an integrated circuit wafer with flash memory and identifying function, comprising a packaging substrate, packaging body, flash memory crystal grains and wireless crystal grains, where the flash memory crystal grains and the wireless crystal grains are arranged on the packaging substrate and packaged by the same packaging body so as to make the integrated circuit wafer posses flash memory and personal identifying function. In addition, the integrated circuit wafer can be connected to a control wafer to provide data read/write and data encryption functions, and as the ID code stored in the wireless wafer grains accords with the identification data contained in the received wireless signal by comparison of the control wafer, it can allow the flash memory wafer grains to access data.
Description
Technical field
The invention relates to a kind of quickflashing memory IC wafer, refer to a kind of integrated circuit (IC) wafer especially with fast flash memory and recognition function.
Background technology
Because fast flash memory does not need electric power to keep the data that has stored, so behind power-off, the data that originally writes still can be stored in the holder, and have more the jumbo characteristic of small size, make fast flash memory be widely used in many portable 3C Products, digital storage card (as CF, MMC, SMCard) that uses as individual action assistant (PDA), wireless mobile communication device (mobile phone, PHS etc.), digital camera collocation or action dish etc., this kind digital storage card or action dish generally are to be carried by the user.In addition, the user also may need to carry many identity recognition devices, as gate inhibition's card, identification card etc., if add aforesaid storage card or action dish, to make user's belongings quantity become very huge, this is quite inconvenient for the user.
Summary of the invention
The present invention is a kind of integrated circuit (IC) wafer with fast flash memory and recognition function, comprising: package substrates, packaging body (body), fast flash memory crystal grain and wireless crystal grain (codeless die); Above-mentioned fast flash memory crystal grain and wireless crystal grain be to be positioned on the package substrates and with identical packaging body to encapsulate, and wireless crystal grain have an identity identification code, and when receiving a wireless signal, return a back-signalling.Therefore, multiple different identity recognition device just can be integrated with fast flash memory crystal grain, makes the integrated circuit (IC) wafer of fast flash memory and recognition function have multiple function.
The integrated circuit (IC) wafer of fast flash memory and recognition function more can be connected to a control crystal grain wafer, control crystal grain wafer can take out the identity code that wireless crystal grain has, and compare with the identification data that wireless signal comprised that wireless crystal grain is received, and when comparison result is consistent, allow fast flash memory crystal grain to carry out data access, so the secret service of can giving information.The integrated circuit (IC) wafer of above-mentioned control crystal grain wafer and fast flash memory and recognition function can be arranged on a circuit board or be integrated on the surface-mounted integrated circuit.In addition, in wireless crystal grain, can there be a plurality of fast flash memory crystal grain in the not corresponding packaging body of multicomponent, make each fast flash memory its identity code separately all be arranged to carry out the security services of data.
Wherein wireless crystal grain is the crystal grain for a radio frequency identification (RFID) crystal grain, tool bar code function ... Deng crystal grain with wireless telecommunications and recognition function.
Above-mentioned wireless crystal grain piles up and places on the fast flash memory crystal grain, and several fast flash memory crystal grain also can pile up each other and be packaged among the same packaging body.
Description of drawings
Fig. 1 is the encapsulating structure schematic diagram of a preferred embodiment of the present invention;
Fig. 2 is the electrical block diagram of a preferred embodiment of the present invention.
Embodiment
Fig. 1 is the encapsulating structure schematic diagram of a preferred embodiment of the present invention, as shown in the figure, integrated circuit (IC) wafer 1 with fast flash memory and recognition function includes: package substrates 10, on package substrates 10, be provided with fast flash memory crystal grain 11 and wireless crystal grain 13 (codeless die), and encapsulate with same packaging body 12 (body), in this example, wireless crystal grain 13 is for a radio frequency identification crystal grain and is stacked and placed on the fast flash memory crystal grain 11, to save shared area; Wireless crystal grain 13 itself has an identity identification code, and when receiving a wireless signal, can return a back-signalling, has comprised the identity code of itself in the back-signalling, so have the function of identification.
Please refer to Fig. 2, Fig. 2 is the electrical block diagram of a preferred embodiment of the present invention, wherein, an integrated circuit (IC) wafer 1 and a control wafer 21 are arranged on one for example on the circuit board 20 that stores card, when carrying out data access with the fast flash memory crystal grain 11 that sees through the 22 pairs of integrated circuit (IC) wafer 1 in interface that store card when host side (scheming not formula), under the control of control wafer 21, need the identity code comparison in the wireless crystal grain 13 of input personal information and integrated circuit (IC) wafer 1 earlier, as be consistent and just can carry out the access of data, thereby reach the function of security document.
By above explanation as can be known; the present invention is encapsulated in fast flash memory crystal grain 11 and wireless crystal grain 13 in the integrated circuit (IC) wafer 1; therefore; the storage card made from this integrated circuit (IC) wafer 1 or with oneself dish itself promptly to can be used as be an identification card; can simplify the required device of carrying of user; simultaneously, also can protect the data that stores card or coil with oneself not read and write arbitrarily, and effectively realize the purpose of data security.
The foregoing description only is to give an example for convenience of description, and the interest field that the present invention advocated is from should but not only limiting to the foregoing description with described being as the criterion of claim of application.
