1-Bit Memory: The Atom of RAM — and the Finale of Building a Computer from Relays
In the previous post, we built the D latch: a circuit that accepts a Data input and a Write-enable line, and faithfully stores whatever it sees on Data at the...

The previous post ended with something genuinely new in this series: a circuit that could remember. The R-S latch, built from two cross-coupled gates, held its output even after the...
In the previous post, we saw what happens when feedback chases itself around a loop with no place to land: the output flips, which triggers a flip back, which triggers...
TL;DR: RAM is volatile read-write memory used as the CPU's working scratchpad; ROM is non-volatile read-mostly memory used to hold firmware and constants. Both are arrays of single-bit cells selected...
