Description

Memory board using universal serial bus control

This creation is about a memory board, especially the electrical function of using a general-purpose serial bus (USB) instead of I2C to control the management of its lighting or the fan, temperature and humidity on the main board by the memory board.

Generally, a memory module configured with a plurality of memory chips is inserted in a memory slot of the motherboard for the central processing unit (CPU) to perform data access operations according to actual needs. With the continuous improvement of half-body technology, DDR and DDR2 have evolved to DDR4 and even DDR5 to meet the requirements of data access and transmission speed.

Taking a server or a personal computer as an example, a plurality of light-emitting diodes (LEDs) are generally arranged on the motherboard, and the change of the light signals is used to display the current operating state of different electrical devices in the system, such as whether the power supply is normally powered. Whether the fan is running, whether the network card is connected, whether the universal serial bus (USB) device is connected, whether the disk drive and the CD player are accessing data, or even whether the temperature and humidity are within the normal range.

On the motherboard, the CPU is connected to the north bridge chip, and then the north bridge chip connects the south bridge chip, the memory module, and the display card, and the south bridge chip responsible for the peripheral device is connected to the disk drive interface (IDE/SATA) and the network card interface. , audio interface, USB bus and other bus, such as the traditional I2C (Inter-Integrated Circuit) bus or SMBUS bus.

Generally, the LEDs of the above motherboard are arranged on the USB bus. Therefore, the CPU can issue control commands via the north bridge chip, the south bridge chip, and the USB bus to control the LED number change on the USB bus. Since the USB operation mode of the whole system is quite stable and mature, including the underlying driver software, operating system (OS) and the uppermost application software (APP), the practical application field has been quite extensive.

For the memory module, since it is inserted in the memory slot, and the configured memory (wafer) is connected to the north bridge wafer and utilizes a specific high speed bus for data access, such a high speed The bus is a multi-bit address line (ADDRESS), a data line (DATA), and an input/output control line (I/O) for data access. However, the CPU can use the traditional I2C bus or SMBUS bus to detect the memory chip, such as the model, capacity and so on, so the LEDs on the memory module are generally controlled by I2C bus or SMBUS bus. Instead of the usual USB bus.

Due to the difference in electrical operation between the USB bus and the I2C bus, the LED lights on the memory module and the LEDs of other modules hanging on the USB bus cannot be synchronized, resulting in mutual The difference is inconsistent, causing the user to feel visually uncomfortable.

Therefore, there is a great need for an innovative memory board that replaces the I2C with a universal serial bus (USB) and controls the electrical function of the lighting, or the management of the fan, temperature, and humidity on the main board by the memory board. Whether the memory LED or the peripheral device LED can accurately generate a consistent specific lamp number change under the control of the CPU, that is, the change of synchronization, does not cause visual discomfort, thereby solving all the problems of the above-mentioned conventional technology.
