Flip-Flops that read in a new value on the rising and the falling edge of the clock are called dual-edge-triggered flip-flops. Such a flip-flop may be built using two single-edge-triggered D-type flip-flops and a multiplexer, or by using two single-edge triggered D-type flip-flops and three XOR gates.
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.
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]
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):
D : Q; where Dff is the D-input of a D-type flip-flop, D is the module information input (without CE input), and Q is the D-type flip-flop output. This type of clock gating is race-condition-free and is preferred for FPGA designs. For FPGAs, every D-type flip-flop has an additional CE input signal.
An asynchronous (ripple) counter is a "chain" of toggle (T) flip-flops in which the least-significant flip-flop (bit 0) is clocked by an external signal (the counter input clock), and all other flip-flops are clocked by the output of the nearest, less significant flip-flop (e.g., bit 0 clocks the bit 1 flip-flop, bit 1 clocks the bit 2 flip ...
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.
individual flip-flops; high-speed core memory; In addition to the "programmer-visible" registers that can be read and written with software, many chips have internal registers that are used for state machines and pipelining; for example, registered memory.
