Embodiment 1

[0018] like figure 1 As shown, lead 10, 12, 22, 24, 28, 30 and other lines in parallel at the 34-pin interface, connect to P0.1~0.5 pins in the controller MCU, and connect P1.0~1.7 from the MCU, For P2.0~2.3, each line is fixedly connected to the 20-wire connector. The controller MCU can be installed on the floppy drive in the host computer or on the back plate of the floppy drive guide in the floppy disk system.

[0019] The flash memory circuit chip port lines VCC, I / O1~O7, CLE, ALE, WE, WP, CE, RE, R / E, R / B, SE, VCCQ, VSS in the flash memory universal mobile disk are solidified on the 20-wire connector , through the corresponding connection with the MCU.

[0020] The signal command of the host enters the MCU of the controller through the 34-pin interface. In the MCU, through its intelligent flip code, the signal of the host is translated into a signal command that the flash memory can recognize, and is transmitted to the universal mobile disk of the flash memory through ...

Embodiment 2

[0025] refer to image 3 , the lead wire of the host USB interface is connected to the MCU of the controller, and the output wire of the MCU is connected to the 20-wire connector, that is, the port wires RMIO1~7 are respectively connected to the data wires I / O1~O7 of the flash memory mobile disk through the 20-wire connector, and the MCU’s Other port lines FMCLS(17), FMALE(16), FMXWR(15), FMXWP(14), FMXCHIP1(18), FMXRD(20), FMRDXBZY(21), SE, VCC5V, GND are respectively connected to flash memory through 20-wire connectors The port line CLE of the mobile disk, ALE , we , WP, CE , RE , R / E, R / B, SE, VCCQ, VSS, the MCU signal lines USB-DM and USB-DP are connected to the USB port lines DATA+ and DATA-, which can realize the computer to read and write the flash memory mobile disk.

[0026] The MCU and the 20-wire connector are also the same as the fixing principle of Embodiment 1 (any position on the host), but the 20-wire connector must ensure reliable connection with the 20...

Embodiment 3

[0029] Can be implemented by implementing 1, 2 structures in new computer production, also can go out F disk special-purpose window on mainframe panel (or other surfaces). according to figure 1 , image 3 connected in a way to form a separate flash F disk external storage system.

Abstract

In the present invention, flash memory circuit is used as storage device of computer and flash memory chip is connected to soft driving interface or / and USB interface through controller to fulfil tasks of storing, fetching, reading and writing for comptuer data under the control of relevant computer software. The present invention also provedes universal movable disc being made according to above application as flash memory circuit chip is inlaid on movable disc.

Description

Technical field: [0001] The present invention is an improvement to the external storage system of the floppy drive and floppy disk of the existing computer, provides a computer external storage method using a flash memory circuit as a storage device, and also discloses an external flash memory device adapted to the method, which belongs to the computer storage technology field. Background technique: [0002] At present, ordinary computer external memory systems generally use magnetic or optical media to make storage elements. Therefore, the external memory system inherently has the following shortcomings: limited by the storage mechanism and quantity of magnetic media, such as: a 3-inch magnetic floppy disk The maximum storage can only reach 1.44M, which cannot meet the requirements of storage and transmission in many cases. It is driven by a mechanical structure, and the failure rate is high. In recent years, the U disk has been invented by utilizing the achievements of hi...
