Problems solved by technology

The problem with this existing testing method using a PC is that the general PC window TM (or MAC TM) operating system only supports some USB devices at a time, and it takes a lot of time for the operating system to detect and test the USB flash card Insert each USB flash card by hand, and then remove each USB flash card by hand
As a result, existing testing methods cannot keep up with the increase in manufacturing output

Embodiment Construction

[0043] The present invention is about an improvement on the method for manufacturing electronic data flash cards. Although the following is a specific reference to USB electronic data flash cards, the innovation of the present invention can be used in a wide range of flash card types. Manufacturing, including PCIExpress, SecureDigital (SD), MemoryStick (MS), CompactFlash (CF), IDE and SATA flash memory cards, but not limited to these flash card types mentioned above.

[0044] Referring to Fig. 1 (A), according to an embodiment of the present invention, an electronic data flash card 10 is passed through an external (host) computer 9 through any interface bus (interfacebus) 13 or a card reader (not shown in the figure) ) or other interface mechanisms (not shown), and the electronic data flash card 10 includes a card body 1, a processing unit 2, one or more flash memory devices 3, an optional fingerprint sensor (security device ) 4, an input / output interface circuit 5, an optiona...

Abstract

A high volume testing / formatting process is provided for Universal Serial Bus-based (USB-based) electronic data flash cards (USB devices) that meets the increasing demand for USB electronic data flash cards (USB devices). A test host is simultaneously coupled to the multiple USB devices (e.g., using a multi-port card reader or a probe fixture), a controller endpoint value is read from each of the USB devices and verified with a known good value, and then testing / formatting is performed on each of the USB devices by writing predetermined data into each USB device in a pipelined manner, then reading out and testing the predetermined data. In one embodiment, the test host implements a special USB driver that blocks standard USB registration procedures upon detecting the plurality of USB devices. Control and / or boot code data are written onto the flash memory device (i.e., instead of being provided on a controller ROM).

Description

technical field [0001] The present invention relates to an electronic data flash card, in particular to a system and method for testing a USB electronic data flash card during manufacture. Background technique [0002] Confidential data files are often stored in a floppy disk drive (floppydisk), or are transmitted through a network that requires passwords or encryption codes to ensure security, and confidential data files will be added with a safety seal (safety seal) and watermark (watermark) during transmission. mark) to send. However, once passwords, encryption codes, security seals and imprints are cracked, confidential data files and documents are exposed to danger, and unauthorized persons can use this confidential information. [0003] As flash memory technology becomes more advanced, flash memory is gradually replacing traditional disk drives as storage media for mobile systems. Flash memory has significant advantages over floppy disk drives or magnetic hard disks,...
