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.
