*NOTE* The Reality Immersion Graphics Processor and Audio Processing Unit are
combined into a single co-processor.

Just in case you don't know, the N64 uses Rambus DRAM. Rambus DRAM is 9-bit
(8 bits of data and 1 parity bit) instead of the usual 8-bit RAM. So, if you
multiply 9 (the number of bits of the RAM) x 4 (the number of megabytes of
RAM in the N64), then you get 36 megabits. Which, when converted to
megabytes, is 4.5 megabytes. But, the N64 actually only has 4 megabytes of
RAM. So, in conclusion, Nintendo is technically correct when they say 36
megabits because that's how many megabits of RAM they have.

Check the Glossary of Terms to find out explanations for what some of the
above technical terms and abbreviations mean.

If you have any technical related questions, comments, etc. please send them
