SGRAM
Last modified: Monday, October 20, 1997
Abbreviation of Synchronous Graphic Random Access Memory, a type of DRAM used increasingly on video adapters and graphics accelerators. Like SDRAM, SGRAM can synchronize itself with the CPU bus clock up to speeds of 100 MHz. In addition, SGRAM uses several other techniques, such as masked writes and block writes, to increase bandwidth for graphics-intensive functions.
Unlike VRAM and WRAM, SGRAM is single-ported. However, it can open two memory pages at once, which simulates the dual-port nature of other video RAM technologies.
Video Memory Technologies Provides a detailed look at the various memory technologies (DRAM, EDO, VRAM, WRAM, SGRAM, and MDRAM) used on video cards. Also contains a comparison of the most common video memory technologies. This page is from "The PC Guide."
