8-bit computer RAM intro
A 14-minute video by Ben Eater about computing mechanisms, on the From scratch shelf. It came up in r/compsci, in a thread called “Need Resources for Computer Orgnization & Architecture”. It is pitched at intermediate level.
Ben Eater, Video, 14 min, 2016, on the From scratch shelf
An introduction to the 16-byte by 8-bit static RAM that we're going to build for our 8-bit computer.
Study notes
Intermediate, Built from scratch. Step 4 of 10 in How a computer works
Helpful first
- Binary numbers
- Logic gates
What it builds
- Organize stored bits into addressable locations.
- Separate address, data and control signals.
- Understand how read and write operations change circuit state.
Useful moments
- 0:20Enable and clock signals for stored bits
- 1:30Eight-bit inputs and outputs
- 7:14Encoding a memory address
Check yourself: Which signals must change to write a value without changing its address?
