C.1.6 Peripherals - Sun Microsystems Enterprise 220R Service Manual

The 3DRAM is a standard dynamic random access memory (DRAM) that includes a
multi-level cache and a separate graphics port. The FBC ASIC provides acceleration
for 2D and 3D imaging primitives. This, combined with the 3DRAM cache and
support for graphics operations, supports a high-performance frame buffer.
