Perhaps the simplest memory device in real applications, the Data Latch is really a Clocked Set-Reset Latch with the inputs R and S tied together through an inverter. more…

The most basic useful feedback sequential circuit is the Set-Reset Latch with NOR gates. The Set-Reset Latch, as you might guess from the name, is a finite state machine more…

The master-slave flipflop design demonstrates one of the most fundamental concepts in modern engineering: Defense in Depth. The basic idea behind the Defense in Depth design philosophy is that you never want to build a system that is vulnerable to a single failure. more…

The Gated Set-Reset Latch (also known as a Clocked SR Latch) is merely a Set-Reset Latch with a doorway. And we put a door on a set-reset latch for the same reasons we might put a door on anything else: to control access. more…
