VRAM (Video RAM) Explained
03 June 2021
VRAM (video RAM), also known as a frame buffer, is used to store the rendering data processed or about to be extracted by the graphics chip. Like computer memory, VRAM is a component used to store graphics information to be processed.
Introduction to Optical Amplifier
27 March 2025
An optical amplifier is a subsystem product that can amplify optical signals in optical fiber communication systems. The principle of the optical amplifier is basically based on the stimulated radiation of the laser, which realizes the amplification effect by converting the energy of the pump light into the energy of the signal light.
Solid State Relay Basics: Working, Features and Structure
17 September 2020
Solid State Relay (SSR) is a non-contact switch composed of microelectronic circuits, discrete electronic devices, and power electronic power devices. The isolation device is used to realize the isolation between the control end and the load end. The input terminal of the solid state relay uses a tiny control signal to directly drive a large current load.
What are Graphene Transistors?
21 October 2025
Graphene is a two-dimensional crystal. Its structure is very stable because carbon atoms are arranged in hexagons and connected to each other to form a carbon molecule.
