	Synchronous graphics RAM (SGRAM) is a specialized form of SDRAM for graphics ~~adaptors~~. It adds functions such as [[bit mask]]ing (writing to a specified bit plane without affecting the others) and block write (filling a block of memory with a single ~~colour~~). 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.

	Graphics double data rate SDRAM is a type of specialized [[Double data rate\|DDR]] [[Synchronous dynamic random-access memory\|SDRAM]] designed to be used as the main memory of [[graphics processing unit]]s (GPUs). GDDR SDRAM is distinct from commodity types of DDR SDRAM such as DDR3, although they share some core technologies. Their primary characteristics are higher clock frequencies for both the DRAM core and I/O interface, which provides greater memory bandwidth for GPUs. As of ~~2020~~, there are ~~seven,~~ successive generations of GDDR: [[GDDR2]], [[GDDR3]], [[GDDR4]], [[GDDR5]], [[GDDR5X]], [[GDDR6]] and [[~~GDDR6X~~]].
