Description

The memory circuit board controlled using universal serial bus

Technical field

The utility model replaces I2C especially with general-purpose serial bus USB and passes through about a kind of memory circuit board Memory circuit board is to control the electric function of the management of fan on its light or mainboard, temperature, humidity.

Background technique

Generally, the memory modules for configuring multiple memory chips are plugged on the memory slot of mainboard, with for centre Reason device (CPU) carries out data access operation depending on actual needs.Memory chip with the continuous promotion of half body technique and by, DDR, DDR2 evolves to DDR4, even DDR5, to meet the requirement in data access and transmission speed.

By taking server or personal computer as an example, it can generally be configured on mainboard multiple light emitting diodes (LED), by cresset The variation mode of operation current with electric devices different in display system, such as power supply unit whether normal power supply, fan Whether operate, whether network card is connected, whether universal serial bus (USB) device has connected, disc driver and CD-ROM drive whether Into data access is carried out, even in the normal range whether temperature, humidity.

On mainboard, CPU is connection north bridge chips, then is adapted to by north bridge chips connection South Bridge chip, memory modules, display Device, and the South Bridge chip for being responsible for peripheral device then connects disk drive interface (IDE/SATA), network card interface, audio and connects Mouthful, usb bus and other buses, such as traditional I2C (Inter-Integrated Circuit) bus or SMBUS it is total Line.

In general, the LED of above-mentioned mainboard is disposed on usb bus, therefore, CPU can be via north bridge chips and south bridge core Piece, usb bus assign control instruction, to control the cresset variation of LED on usb bus.Due to the USB mode of operation of whole system It is quite stable, mature, the application software (APP) of drive software, operating system (OS) and top layer comprising bottom, so real In the application field of border quite extensively.

For memory modules, due to being that the memory (chip) being plugged in memory bank, and configured is attached to north bridge To carry out data access on chip and using specific high-speed bus, and this kind of high-speed bus is the money address wire comprising multidigit (ADDRESS), data line (DATA), input and output control line (I/O) are for data access.But, CPU can be utilized traditional I2C bus or SMBUS bus are to detect memory chip, for example obtain model, capacity etc. information, so on memory modules LED is usually controlled using I2C bus or SMBUS bus, rather than common usb bus.

Since usb bus and I2C bus are in the otherness of electric operation, the LED light number on memory modules can be made and hung The LED light number of other modules on the usb bus is unable to reach synchronization, causes to have drop between each other and inconsistent, causes to use Family visually generates sense of discomfort.

Hence it is highly desirable to which a kind of memory circuit board of innovation, is to replace I2C with universal serial bus (USB) and pass through Memory circuit board is to control the electric function of the management of fan on its light or mainboard, temperature, humidity, thus whether memory LED or peripheral device LED can accurately generate the specific cresset variation of consistency, that is, synchronous variation under the control of cpu, It not will cause visual sense of discomfort, use all problems for solving above-mentioned common technology.
