Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. [1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.
The TMS9918A's method of accessing the video RAM is slower than direct access, as used in unified-memory computers, because accessing video memory involved first outputting the low- then the hi-byte of the (14-bit) video memory address to I/O port $99, then one or more bytes of 8-bit data to port $98.
The 1280 × 1024 resolution became popular because at 24 bit/px color depth it fits well into 4 megabytes of video RAM. [citation needed] At the time, memory was extremely expensive. Using 1280 × 1024 at 24-bit color depth allowed using 3.75 MB of video RAM, fitting nicely with VRAM chip sizes which were available at the time (4 MB):
