History

In the old days of computers, they used expensive and fast memory to show pictures on the screen. But as technology improved, they found a cheaper type of memory called DRAM.

DRAM was a bit slower, but they made special graphics controllers to help it work well for graphics.

Then came the cool thing called Dual-Port VRAM. It had two doors that the graphics part and the display part could use at the same time. This made things much faster and improved graphics performance.

After that, they introduced Multiport VRAM and SGRAM.

Multiport VRAM had even more doors, which meant even better graphics performance.

SGRAM was like a smart version of VRAM that could talk to the computer’s graphics card more efficiently.

Next up was DDR VRAM. It was like the DDR memory used in computers but tweaked for graphics. DDR VRAM was faster, making graphics look smoother and better.

Around the 2000s, GDDR VRAM became the standard. It was an improved version of DDR VRAM, and it kept getting better with different generations like GDDR2, GDDR3, and so on.

GDDR VRAM was perfect for graphics cards and made video games and other graphics-heavy tasks work really well.
