Description

Memory circuit board controlled by universal serial bus

Technical Field

The invention relates to a memory circuit board, in particular to an electrical function for controlling light or management of a fan, temperature and humidity on a mainboard of the memory circuit board by using a Universal Serial Bus (USB) to replace an I2C.

Background

Generally, a memory module configured with a plurality of memory chips is inserted into a memory slot of a motherboard for a Central Processing Unit (CPU) to perform data access operations according to actual needs. With the development of half-chip technology, DDR and DDR2 have evolved into DDR4, 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 disposed on a motherboard, and the current operating states of different electrical devices in the system, such as whether a power supply is supplying power normally, whether a fan is running, whether a network card is connected, whether a Universal Serial Bus (USB) device is connected, whether a disk drive and an optical drive are accessing data, and even whether the temperature and humidity are within normal ranges, are displayed by the change of signals.

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

Usually, the LEDs of the motherboard are disposed on the USB bus, so the CPU can issue control commands through the north bridge chip, the south bridge chip and the USB bus to control the lamp number variation of the LEDs on the USB bus. Since the USB operation mode of the whole system is quite stable and mature, and includes the bottom driver software, the Operating System (OS) and the top application software (APP), the USB operation mode has been quite wide in the field of practical application.

For the memory module, the memory module is inserted into the memory slot, and the configured memory (chip) is connected to the north bridge chip and uses a specific high-speed bus for DATA access, and the high-speed bus includes multi-bit DATA ADDRESS lines (ADDRESS), DATA lines (DATA), and input/output control lines (I/O) for DATA access. However, the CPU can detect the memory chips by using the conventional I2C bus or SMBUS bus, for example, to obtain the information of model, capacity, etc., so the LEDs on the memory module are generally controlled by using the I2C bus or SMBUS bus, rather than the conventional USB bus.

Due to the difference in electrical operation between the USB bus and the I2C bus, the LED signals of the memory module and the LED signals of the other modules hung on the USB bus cannot be synchronized, which causes a difference between them and causes a visual discomfort to the user.

Therefore, an innovative memory circuit board is needed, which uses a Universal Serial Bus (USB) to replace I2C and controls the electrical functions of the light or the management of fan, temperature and humidity on the motherboard through the memory circuit board, so that no matter whether the memory LED or the peripheral device LED can precisely generate consistent specific light signal changes, i.e. synchronous changes, under the control of the CPU, no visual discomfort is caused, thereby solving all the problems of the conventional technologies.
