In an embodiment of the controller, the controller causes the sockets 120-12N to respectively record the recording files into the memory chips 200-20N in a synchronous manner. But the present invention is not limited thereto. It should be noted that, in this embodiment, the recorder 100A burns the recording files into the memory chips 200 - 20N in parallel. For example, each memory chip 200 - 20N has a predetermined number of transmission pins respectively. Therefore, the sockets 120 - 12N also have the same predetermined number of transmission pins, and the predetermined number is greater than one to implement parallel transmission. The recorder 100A uses a predetermined number of transmission pins to transmit or download recording files to the memory chips 200-20N at the same time, so as to shorten the data recording time. In addition, it should be noted that in this embodiment, the sockets 120-12N need to be customized according to the versions of the memory chips 200-20N. However, the socket has a limited lifespan, and usually needs to be replaced with a new socket after multiple recordings, so the cost of the socket will increase accordingly.

The clamp 400C is used to fix the circuit board and the connector at a specific position, so as to facilitate the docking of the connector and the memory chip with thimbles. In an embodiment, each controller is used to correspond to one of the parallel data transmission connectors 130 - 13N, and write to a memory chip 200 - 20N coupled to the corresponding parallel data transmission connector, but the invention is not limited thereto. The parallel data transmission connectors 130-13N respectively include parallel transmission lines PLC11-PLC1N, wherein the parallel data transmission connectors 130-13N are respectively coupled to the parallel data transmission connectors 420-42N fixed by the clamp 400C through the parallel transmission lines PLC11-PLC1N.

Fixture 400C includes a plurality of parallel data transmission connectors 420-42N and a plurality of parallel transmission lines PLC21-PLC2N. Parallel data transmission connectors 420-42N are used to receive recording files transferred in parallel from the parallel transmission lines PLC11-PLC1N, and burn the recording files to the installed (welded) circuit in parallel through the parallel transmission lines PLC21-PLC2N Memory chips 200-20N on board 500-50N (420-42N and PLC11-PLC1N are just transmission lines).

It should be noted that, in this embodiment, the recorder 100C burns the recording files to the memory chips 200 - 20N in parallel.

In detail, the clamp 400C is used to fix the circuit board 500-50N, so that the recorder 100C can record the record file into the memory chip 200-20N. For example, the jig 400C may have a plurality of platforms (not shown) for fixing the circuit boards 500-50N respectively, and a plurality of thimble pins (not shown) for coupling to the soldered circuit boards 500-50N respectively. The pins of the memory chips 200-20N, wherein the thimble pins (not shown) in the fixture 400C are used to connect with the corresponding pins of the memory chips 500-500N respectively. It is worth noting that, in this embodiment, the recorder 100C can record the recording files to the memory chips 200-20N in parallel, and because the clamp 400C is used, the recording system 1000C saves the high socket 120-12N. cost. Therefore, compared with the recording system 1000A, the recording system 1000C has a lower cost, and compared with the recording system 1000B, the recording system 1000C has a faster recording speed.

In an embodiment of the present invention, the recording file is a packaged document in a specific format. For example, the burning file is a file packaged in MTX mode, but the present invention is not limited here. In addition, in an embodiment of the present invention, the memory chips 200-20N are memory modules, but the present invention is not limited thereto. For example, the memory chips 200-20N can be any combination of a controller and a flash memory (flashrom), such as eMMC (Embedded Multi Media Card) memory chips, eMCP (Embeded Multi-Chip Package) memory chips, UFS (Unix File System) format memory chips and so on. In addition, the recording system 1000C is especially suitable for recording large memory modules with a controller. Because, the burn files of large memory modules with controllers are large and tend to take longer to burn. Using the recording system 1000C to record large memory can save relatively more time and cost, but the present invention is not limited thereto. The recording system 1000C also has relatively fast speed and relatively low cost among other types of memory chips.

For example, as shown in FIG. 5, when the memory chip 200-20N is an eMMC memory, there are 14 necessary pins of the memory chip 200-20N, including 8 data lines (DATA0-DATA7), a frequency line ( CLKm), a reset line (RST), a command line (CMD), a ground line (GND), and two power lines (VCC1 and VCC2). In other words, each of the parallel transmission lines PLC11-PLC1N, PLC21-PLC2N, PLB1-PLBN has the above-mentioned 14 transmission lines, respectively. However, the serial transmission lines SLB1-SLBN using the USB interface only have 5 transmission lines, and only two of them are data lines for transmitting data. Under the above conditions, the recording speed of the recording system 1000C is 10-24 Mbytes per second, and the recording speed of the recording system 1000B is 5 Mbytes per second. Compared with the recording system 1000B, the recording speed of the recording system 1000C is about 2-5 times faster than that of the recording system 1000B. In addition, the cost of the recording system 1000C is reduced by approximately 54.5% compared with the cost of the recording system 1000A because there is no need to replace the socket. It should be noted that the user can choose a suitable embodiment provided by the present invention to implement according to the requirements of the product, and the present invention is not limited thereto. In addition, the recording system 1000A records recording files into the memory chips 200-20N before the memory chips 200-20N are soldered to the circuit board 500-50N. However, the recording system 1000B and the recording system 1000C record recording files into the memory chips 200-20N after the memory chips 200-20N are soldered to the circuit board 500-50N. Burning is performed after the memory chip 200-20N is soldered to the circuit board 500-50N, so as to avoid the risk of data loss during the high-temperature soldering process. In addition, in one embodiment, the recorder 1000C can be used to record at least four recording files into at least four memory chips respectively. In another embodiment, the recorder 1000C can be used to record more than eight recording files into more than eight memory chips respectively.
