[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a nonvolatile fixed state storage driver having functions of various nonvolatile fixed state memory bus arrays connected to a volatile fixed state memory driver of a PC main board through electricity.

[0002]

[Prior art]

 In the past, computer memory used magnetic media to store teledata, and computer soft disks and hard disks were all equipped with magnetic media storage devices. Although magnetic storage devices were very convenient with high-capacity memory, they had problems with short service life and certainty.

[0003] Furthermore, conventional portable storage devices cannot achieve the purpose of true mobile storage, and are mostly bulky and inconvenient to carry, such as external hard disks, recording devices, ZIP, MO, etc. It can provide large storage, but lacks mobility. Portable memories such as soft disks have the disadvantage that dedicated drivers occupy a large volume, consume power, are noisy, respond slowly, and can easily be physically damaged when used.

[0004] With the development of semiconductor technology in recent years, nonvolatile fixed-state memory capacity has been gradually increased, prices have become lower, and fixed-state storage disks have increased the reliability of computer operation and data in place of soft disks or hard disks. . There are a wide variety of current fixed state storage disks, including CF cards, MMC cards, SMA cards, and non-volatile fixed state memory disks with a USB interface, which exchange data with a PC through the interface. On the other hand, a PC generally uses a hard disk as a storage medium and provides a guide operation through the hard disk. In order to achieve the desired function individually, such as installing a new system or using an operating system that does not currently exist, the user may perform a guide operation through a soft driver, and in general, an opportunity for the user to guide with a soft disk The function is one of the essential functions, though it is extremely few.

[0005]

[Problems to be solved by the invention]

 However, non-volatile fixed state memory is simply data memory and cannot be used as a system guide device. As a result, the guide device identification of the standard data format of the computer BIOS is now magnetic data format, and the non-standard nonvolatile fixed-state memory data format cannot be used as the system guide device, and the nonvolatile fixed format cannot be used. State memory could not solve the problem of conventional drivers.

Further, the structures of various cards are different, and the PC has to be provided with various interfaces in order to safely connect to the above-mentioned nonvolatile memory. In this case, the number of electrical connection interfaces on the PC main board increases, complicating the structure of the PC or other external devices, and the interface position of the conventional non-volatile memory is always a single position on the PC, which is not practical. Influenced sex.

Therefore, the present invention is compatible with various nonvolatile fixed state memory drivers, and can be connected to a computer throughout the conversion period, provided in a host computer or other connected devices, inserted into a nonvolatile memory, The purpose is to be able to be directly a system guide disc.

Specifically, the conversion electronics consist of a CPU, a buffer, and a bus array signal converter, and the buffer and the bus array signal converter are each connected to a CPU junction line. The driver consists of an interface sheet, the main board provides the control and conversion electronics for the memory, and the PCI, ISA plug-in card provides the control or conversion electronics.

One or several types of conversion electronics in the fixed disk driver support the IDE / soft disk driver interface USB / IEEE 1394 / PCI / ISA interface and are provided in the main body or on the main board . The memo reader body 1 provides one or more USB outlets 2 and a disc-type card outlet 3.

On the electrical side, PDAs and digital camera memory cards, CFs, smart media cards, SMCs, multimedia cards, MMCs, security disks, SDs, memory sticks, USB flash disks, UFD can be used. The transmission of the conversion electronics communicates with the main board through U3's USB DP, USB DM.

The driver simultaneously supports five card functions of MMC, microdiver, MD, SD, CF, and SMC, and transfers data between the computer and the card. The operation methods of the five types of cards are similar, and the condition of the inserted card provided in the main body is inspected and measured, and the inserted state of the card is inspected and measured by the guide lead. Read the data and execute the data transfer process. Of the five types of cards, MMC and SD, CF and MD have good compatibility, and there are only three types of card pedestals. As shown in the electronic circuit diagram, J1 is a USB junction, J3 is a CF insertion pedestal, J2 Is an MMC insertion pedestal, J4 is an MMC insertion pedestal. The control guides for the three types of cards are MMC, CHK, SMC CD, and CF CD, respectively. The electronic circuit operating voltage for the main chip and the CF card is 5V DC, except for the other parts. Are all 3.3 VDC.

U1 and U5 are 8-bit bus array signal converters, which can convert 5V signals and 3.3V signals to each other, and the main chip and the CF card are convenient for communication of other parts. U2 and U4 are two buffers that perform data lock and save control. In the conversion electronics, the three types of card pedestals monitor the card insertion status using the MMC CHK, SMC CD, and CF CD control guides, respectively. When the card is not inserted, the guide is at a high electrical frequency, when the card is inserted into the card base, the control pins change to a low electrical frequency, and the data is read from the card at the same time that the card is inserted and inspected and measured. , Data is transmitted through the data line.

CF card: CF card itself has a data storage function, U3 controls the address selection of J3 CF card by three access lines CF-A0, CF-A1, CF-A2, CF- # RE, ST9- # WE Internet control card read / write operation and CF R / B pin to check if card operation status is ready or busy, and finally execute data transmission by eight data lines ST9-D0-ST9-D7 I do.

MMC card: MMC data transmission format is series data transmission, MMC-CLK receives time signal, and MMC-DAT pin receives data signal. Due to the effect of the transmission format, the determined signals and data cannot be received directly through U3, but the data is buffered and stored by U2 and U4.

SMC: The data transmission format of SMC is parallel data transmission. U1 and U5 are used to control the signal between U3 and perform data signal lock and transmission. U1 controls the signal receiver / transmitter in the electronic circuit, U5 uses it as the data receiver / transmitter, and the ST9-DATA-DIR net from U3 controls the transmission device and signal flow. When the signal is not yet transmitted, the data is locked, and when the signal is transmitted, the data is transmitted and the data transmission method is bidirectional.

When the present invention is used as a guide disk, the driving part can be formed on the main board or in the driver. After the memory is inserted into the computer, the driver checks the setting of the switch-on procedure through a driver and enters the optical driver or soft disk driver.
