Many modern GPUs rely on VRAM. In contrast, a GPU that does not use VRAM, and relies instead on system RAM, is said to have a unified memory architecture, or shared graphics memory. System RAM and VRAM have been segregated due to the bandwidth requirements of GPUs, [2] [3] and to achieve lower latency, since VRAM is physically closer to the GPU ...
On February 20, 2013, it was announced that the PlayStation 4 would use sixteen 4 Gb GDDR5 memory chips for a total of 8 GB of GDDR5 @ 176 Gbit/s (CK 1.375 GHz and WCK 2.75 GHz) as combined system and graphics RAM for use with its AMD-powered system on a chip comprising 8 Jaguar cores, 1152 GCN shader processors and AMD TrueAudio.

The first graphics cards to use GDDR6X are the Nvidia GeForce RTX 3080 and 3090 graphics cards. PAM4 signalling is not new but it costs more to implement, partly because it requires more space in chips and is more prone to signal-to-noise ratio (SNR) issues, [24] which mostly limited its use to high speed networking (like 200G Ethernet). GDDR6X ...
Increasing memory bandwidth, even while increasing memory latency, may improve the performance of a computer system with multiple processors and/or multiple execution threads. Higher bandwidth will also boost performance of integrated graphics processors that have no dedicated video memory but use regular RAM as VRAM.
Dual-ported video RAM (VRAM) is a dual-ported variant of dynamic RAM (DRAM), which was once commonly used to store the framebuffer in graphics adapters. Dual-ported RAM allows the CPU to read and write data to memory as if it were a conventional DRAM chip, while adding a second port that reads out data.
High Bandwidth Memory (HBM) is a computer memory interface for 3D-stacked synchronous dynamic random-access memory (SDRAM) initially from Samsung, AMD and SK Hynix.It is used in conjunction with high-performance graphics accelerators, network devices, high-performance datacenter AI ASICs, as on-package cache in CPUs [1] and on-package RAM in upcoming CPUs, and FPGAs and in some supercomputers ...
A notable exception was the IBM PC. Graphics display was facilitated by the use of an expansion card with its own memory plugged into an ISA slot. The first IBM PC to use the SMA was the IBM PCjr, released in 1984. Video memory was shared with the first 128 KiB of RAM. The exact size of the video memory could be reconfigured by software to meet ...
CMD4=1 to open (activate) the specified row; CMD4=0 to use the currently open row; CMD3=1 to transfer an 8-word burst; CMD3=0 for a 4-word burst; CMD2=1 for a write, CMD2=0 for a read; CMD1=1 to close the row after this access; CMD1=0 to leave it open; CMD0 selects the DCLK pair to use (DCLK1 or DCLK0)
