Term Definition
3D-RAM

Released by Mitsubishi in July 1994. 3D-RAM is modified version of CDRAM with added arithmetic logic unit doing blending, depth check, stencil and raster operations. It's four bank SDRAM with 2 Kbits of SRAM cache and an arithmetic logic unit (ALU) all on a single chip. Used only on professional graphic cards.

AGP 8x

Accelerated Graphics Port released by Intel in 2002. Width 32bit, clock 66MHz, 0,8V, 2133MB/s

CDRAM

Cache DRAM invented by Mitsubishi. It's DRAM with integrated SRAM cache. Used only on professional graphic cards as texture memory.

EDO

Extended Data Out RAM invented by Micron Technology in 1994. Allows a new memory access to start before the last memory access has finished = lower latencies than FPM. Used till 1998.

MCA

Micro Channel Architecture released by IBM in 1987. Width 16/32bit, clock 10MHz, 5&12V, 66MB/s

MDRAM

Multibank DRAM invented by MoSys in 1994. Used by Tseng in 1996.

NuBus

Developed at MIT, released by Western Digital for their NuMachine. Became a standard in 1987. Width 32bit, clock 10MHz, 40MB/s. Later version NuBus90 had clock 20MHz, 80MB/s.

PCI

Peripheral Component Interconnect released by Intel in 1993. Width 32bit, clock 33MHz, 3,3&5V, 133MB/s
