What is SGRAM?
| Synchronous Graphics RAM |
|
Video memory that includes graphics-specific read / write features. SGRAM allows data to be retrieved and modified in blocks instead of individually. Blocking reduces the number of reads and writes the memory must perform and increases the performance of the graphics controller. A variant of SDRAM, SGRAM makes use of block-write and mask-write functions to increase video-processing speeds. SGRAM is single-ported, so the processor cannot write to it at the same time an image is being refreshed. SGRAM is used in high-end graphics cards, notably those from Matrox Graphics. |
