Problems solved by technology

because figure 1 and figure 2 Due to the limitation of the installation position of memory components and the narrow board circuit substrate, the prior art implements wiring with the shortest distance, which will make the wiring method of the bus signal line a non-equidistant wiring method, which not only easily causes noise interference, but also in UHF Under the operation of the bus, there may be a time difference between the bus signal lines due to unequal line lengths. Therefore, the above two conventional wiring techniques are limited by the narrow board circuit substrate structure, and cannot increase the memory capacity and storage capacity of the display card. Bus bandwidth makes data processing slower

Abstract

The provided RAM-bus routing structure for narrow-board show card comprises: a base plate with multi-layer structure, a display chip, multiple memories, and signal wire. This invention can improve the defect of lacking bus frequency width in prior art.

Description

technical field [0001] The invention relates to a memory bus wiring structure and wiring method, in particular to an equidistant wiring structure and wiring method implemented in a narrow board display card. Background technique [0002] With the advancement of the electronic industry, people have more and more demands on computers, often in order to meet the characteristics of lightness, convenience, space-saving and efficiency, etc., so the computer structure is getting smaller and smaller, and, as electronic devices become more and more Therefore, for the design of the circuit substrate, especially for the wiring method of the signal lines, it is one of the main issues. If the user is using a mini computer or other computers with a small internal space in the casing, it is often impossible to use some computer software due to the insufficient memory capacity and memory bandwidth of the existing narrow board graphics card. [0003] According to the current wiring technolo...
