Description

A DRIVER FOR NON-VOLATILE SOLID-STATE MEMORY}

The present invention relates to a nonvolatile solid state memory driver, and more particularly to a solid state memory driver electrically connected to a PC main board. The driver is provided with the functionality of the conversion bus array interface.

Computer memory uses magnetic media to store data. Recently available computer soft disks and hard disks are magnetic media storage devices. Magnetic media including storage aid in the manufacture of high capacity memories, but the life of the media is short and the reliability is low. This is a disadvantage of magnetic media.

In all recent available mobile memories, the practical purpose of mobile memories has not been achieved. As a result, bulky memories, such as externally mounted hard disks, externally mounted engraving and recording devices, ZIPs, MOs, etc., are inconvenient to carry. These devices provide greater storage capacity, but their mobility is not sufficient. If these devices are used as portable memory, for example as soft disks, they will occupy more space in the drivers utilized specifically, resulting in greater energy consumption and noise. Since the operating speed of the soft disk driver is slow, the storage space is small, and the data storage device is low in reliability. Unlike the unsafe nature of magnetic media as storage media, soft disks are portable products and physical damage is easily found.

With the development of semiconductor technology, the capacity of nonvolatile solid state memory has become larger, but the price of the memory is decreasing. Under these technical circumstances, using solid state memory to replace a soft disk or hard disk will significantly improve the computer's operational and data reliability. There are many kinds of memory, such as CF cards, MMC, SMA cards, and other nonvolatile solid state memories with USB interfaces. These cards are connected to a PC via separate interfaces for data exchange.

On the other hand, a PC uses a hard disk as a memory medium, and guides through the hard disk. In some situations, the customer uses a soft driver to guide the operation to achieve a partial purpose, for example installing a new system or utilizing an operating system that is not currently available. Although the customer may not have the opportunity to use the soft disk driver to proceed with the guide operation, the guide function is one of the basic functions that cannot be ignored. The existing non-volatile solid state memory simply provides data memory but cannot be used as a guide for the system. As a result, the shortcomings of the application of nonvolatile solid state memory to replace existing drivers have not been adequately addressed.

Further, due to the fact that the structure of each kind of card is different, the PC needs to have various kinds of interfaces in order to satisfy the connection of the above-mentioned solid state memory. In this case, the housing of the PC will be very complicated since the number of electrical connection interfaces on the PC main board must be increased. In addition, the location of the interface of the existing solid state memory is a single location, always on the PC, which will affect the active application of the PC.

It is therefore an object of the present invention to provide a driver for a nonvolatile solid state memory which is compatible with other types of solid state memory drivers, which is connected to a computer via a converter and is actively located on a host computer or other externally connected device. It is.

Another object of the present invention is to provide a driver for a nonvolatile solid state memory in which the solid state memory inserted into the driver can function directly as a guide disk of the system.

One aspect of the present invention is directed to a driver for a nonvolatile solid state memory device having a seat body for a nonvolatile solid state memory and an electrical interface for data exchange, wherein the data exchange electrical interface is connected to a computer main board through a conversion circuit. It is characterized by.

Other objects and advantages of the present invention will become more apparent from the following detailed description when read in conjunction with the accompanying drawings.

1 and 2, a non-volatile solid state memory driver is shown that includes an engaging seat body 1 and a data exchange electrical interface B within the body 1. The electrical interface B is connected to the computer main board via the conversion circuit A. FIG. The data exchange electrical interface B includes a CF card interface or an MMC interface, or an SD card interface, an SMC interface, a micro driver (MD) card interface or a USB interface. The output of the conversion circuit A is connected to the main board through the USB interface C or the IEEE 1394 bus array. The conversion circuit includes a CPU, a buffer, and a bus array signal converter, each of which is connected to a CPU junction. If the driver includes only interface sheets, the main mode provides some circuitry for the control and translation of memory, or the PCI or ISA insert card provides control of the translation circuitry.

Fixed Disk Driver Support IDE / Soft Disk Driver Interface Including Electronic Wires The location of one or several types of conversion circuitry within the USB / IEEE 1394 / PCI / ISA interface may be located within the card bite seat body or main board. The memory driver body 1 is provided with one (or more than one) USB insertion hole 2 and a disk type card insertion hole 3.

Cards such as a Compact Flash (CF) card, a Smart Media Card (SMC), a Multi-Media Card (MMC), a Security Disk (SD), a Memory Stick, and a USB Flash Disk (UFD) may be used electrically. The output of the conversion circuit passes through U3's USB DM, USB DP and main board for communication.

The driver has the ability to simultaneously support five cards: MMC, MD, SD, CF, and SMC. The operation modes of the five types of cards are the same. The bite sheet is checked for the state of the card being bitten, and each of them checks the state of the inserted card using a guiding leg.

If an inserted card is detected, the data is accessed and the data is transferred. Of the five types of cards, MMC and SD are compatible and CF and MD are compatible. Thus, there are only three types of bite sheets as shown in the figure, where J1 is the USB junction, J3 is the CF insertion site, J2 is the SMC insertion site, and J4 is the MMC insertion site. Three types of cards of this control guide are MMC CHK, SMC CD and CF CD. The working voltage of the partial circuits of the main chip and the CF card is DC 5V, whereas the working voltage of the other partial circuits is DC 3.3V.

According to the present invention, U1 and U5 are 8-bit bus array signal converters. That is, the 5V signal and the 3.3V signal are mutually converted to help the main chip and the CF card communicate with other parts. U2 and U4 are two buffers used for data locking and storage device control. In the conversion circuit, the three types of bites use the MMC CHK, SMC CD and CF CD control guides respectively to monitor the insertion state of the card. Before the card is inserted, the guide is in a high electrical frequency state, and when the card is inserted in the corresponding place, the control pin is changed to the low electrical frequency so that the inserted card is detected. In this case, data is accessed from the card and data is transferred by the data line.

CF card: Due to the fact that CF owns the data storage function, U3 uses three address lines: CF-A0, CF-A1, CF-A2 to control the address selection of the CF card, CF, #RE, The ST9- # WE network is used to control card read-write operations, and the CFR / B pins are used to determine whether the card operation status is Ready or Busy. As a result, eight data lines, i.e., ST9-DO-ST9-D7, are used to proceed with data transfer.

MMC: The MMC's data transfer format is serial data transfer, the MMC-CLK receives the clock signal, and the MMC-DAT pin receives the data signal. Due to the influence of the transmission format, signals and data cannot pass directly through U3 for reception. Thus U2 and U4 are used to proceed with data buffering and storage.

SMC: The data transfer format of SMC is parallel data transfer. U1 and U5 are used in conjunction with U3 for control of the signal and for locking, storing and transmitting parallel data signals. In the circuit, U1 is used as a device for receiving and transmitting a control signal. U5 is used as a device for receiving and transmitting data from U3, and Network ST9 DATA DIR from U3 controls the conduction of its signals. If this signal is not triggered, the data is locked and stored. When this signal is triggered, data is transmitted, and the format of the data transmission can be conducted in both directions.

When a nonvolatile solid state memory is used as the guide disk, the driver may be located on the main board and also in the driver. If the memory is inserted into the computer after passing through the driver, check the setting of the switching ON sequence and insert the optical driver or soft disk driver.

The BIOS generates an inquiry signal at the driver junction to check the format of the device on the driver junction. If the device responds as a standard device, the BIOS adjusts the standard device installed therein to start the program. The driver can then be set up as a standard guide device.

Referring to Figures 3-8, the mounting of drivers on a computer and other externally connected devices is shown.

3 and 4, the bite sheet body 1 is positioned on the host device 4 or the display 5, which bite sheet body 1 has two independently mounted insertion holes, for example. For example, a USB insertion hole 2 and a disc type insertion hole 3. The bite seat body 1 is located on the operation and control panel 41 of the host device 4 or on the side close to the lower part 51 of the display 5, which facilitates insertion and dial out operations. . It can also be mounted directly on the housing of the computer, for example a keyboard or mouse or a handheld board or voice box. These externally connected devices are provided with a USB interface for connection with a host that can fully support driver data exchange.

5, the driver is located on the keyboard 6, and two insertion holes of the bite seat body, for example, a USB insertion hole 2 and a disc type insertion hole 3, are mounted separately. The insertion direction is from top to bottom, from front to back, from back to front, from left to right, or from right to left.

Referring to Fig. 6, a driver is shown on a handwritten board. 7 shows a driver 1 positioned on a mouse. 8 shows a driver located on the voice box, wherein the insertion holes of the bite seat body are two individually positioned holes, namely a USB insertion hole 2 and a disc type insertion hole 3.

According to the present invention, the insertion holes of one or more bite seat bodies are integrally mounted or individually mounted, and the driver circuit or the conversion circuit of the driver can be used as a module, which circuit is externally mounted on the keyboard. . It can also be formed as an integrated chip integrated with circuitry mounted external to the keyboard. The interface may be USB or IEEE 1394. The concept of circuit arrangement is the same as in other preferred embodiments. The memory inserted into the driver may be one or more of the following components.

a. Compact Flash Card
