Sequential Logic Concepts

Flashcards covering key concepts and definitions related to sequential logic, flip-flops, registers, RAM, and counters in computer architecture.

Combinational Logic

Chips that compute functions based solely on combinations of their input values, without memory.

Sequential Logic

Chips that maintain state and depend on past input values, allowing for memory and time-dependent behavior.

Flip-Flop (DFF)

The most basic sequential element in computers, it holds a single bit of data and changes output according to the clock pulse.

Clock Cycle

The time interval between two consecutive changes of the clock signal, representing one discrete time unit.

Register

A storage device that can remember a value over time, implemented using flip-flops.

Random Access Memory (RAM)

A type of memory that allows the storage and direct access of data words in any order, irrespective of their physical location.

Counter

A sequential chip that increments its state in each clock cycle, typically used in CPU architecture.

Multiplexor (Mux)

A device that selects one of several input signals and forwards the selected input to a single output line.

Addressing

The method of referencing specific locations in memory, allowing access to stored data.

Time Dependence in Circuits

A property wherein the behavior of sequential chips is influenced by previous inputs and states due to clock cycles.
