  2. Flip-flop (electronics) - Wikipedia

    en.wikipedia.org/wiki/Flip-flop_(electronics)

    The term flip-flop has historically referred generically to both level-triggered (asynchronous, transparent, or opaque) and edge-triggered (synchronous, or clocked) circuits that store a single bit of data using gates. [1] Modern authors reserve the term flip-flop exclusively for edge-triggered storage elements and latches for level-triggered ones.

  3. Static random-access memory - Wikipedia

    en.wikipedia.org/wiki/Static_random-access_memory

    Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory; data is lost when power is removed. The static qualifier differentiates SRAM from dynamic random-access memory (DRAM):

  4. Memory cell (computing) - Wikipedia

    en.wikipedia.org/wiki/Memory_cell_(computing)

    Modern random-access memory (RAM) uses MOS field-effect transistors (MOSFETs) as flip-flops, along with MOS capacitors for certain types of RAM. The SRAM memory cell is a type of flip-flop circuit, typically implemented using MOSFETs. These require very low power to maintain the stored value when not being accessed.

  5. Shift register - Wikipedia

    en.wikipedia.org/wiki/Shift_register

    A shift register is a type of digital circuit using a cascade of flip-flops where the output of one flip-flop is connected to the input of the next. They share a single clock signal, which causes the data stored in the system to shift from one location to the next.

  6. Metastability (electronics) - Wikipedia

    en.wikipedia.org/wiki/Metastability_(electronics)

    Synchronizers may take the form of a cascade of D flip-flops (e.g. the shift register in Figure 3). [7] Although each flip-flop stage adds an additional clock cycle of latency to the input data stream, each stage provides an opportunity to resolve metastability. Such synchronizers can be engineered to reduce metastability to a tolerable rate.

  7. Excitation table - Wikipedia

    en.wikipedia.org/wiki/Excitation_table

    Flip-flop excitation tables [ edit ] In order to complete the excitation table of a flip-flop , one needs to draw the Q(t) and Q(t + 1) for all possible cases (e.g., 00, 01, 10, and 11), and then make the value of flip-flop such that on giving this value, one shall receive the input as Q(t + 1) as desired.

  8. Processor register - Wikipedia

    en.wikipedia.org/wiki/Processor_register

    A register-transfer level (RTL) description of an 8-bit register with detailed implementation, showing how 8 bits of data can be stored by using flip-flops.. A processor register is a quickly accessible location available to a computer's processor. [1]

  9. Random flip-flop - Wikipedia

    en.wikipedia.org/wiki/Random_flip-flop

    Random flip-flop (RFF) is a theoretical concept of a non-sequential logic circuit capable of generating true randomness. By definition, it operates as an "ordinary" edge-triggered clocked flip-flop , except that its clock input acts randomly and with probability p = 1/2. [ 1 ]
