SR-LatchFlip-FlopA low voltage and low power SR-latch based flip-flop design is proposed. It is adapted from a classic text-book-style all-NAND based flip-flop design and achieves circuit simplification by eliminating redundant logic. The optimization measure leads to a new design featuring ...

We need to develop a mechanism to trigger the latch inFigure 2and make it change state. This is achieved by the SR (set/reset) latch shown inFigure 3. The SR latch is created by cross-coupling two NAND gates. As we’ll discuss below, the SR latch allows us to store one bit of i...
When designed with NOR gates, the latch is an active high S-R latch, meaning it is set when S = 1. When designed with NAND gates, it becomes an active low S-R latch, meaning it is set when S = 0. The SR Flip Flop is also called a SET RESET Flip Flop. The figure below show...
The block output logic level is either HIGH or LOW, according to the logic levels of the gate inputs and the S-R latch truth table. SR Q n 0 0 Q n-1 0 1 0 1 0 1 1 1 0 The block models the gate as follows: The gate inputs have infinite resistance and finite or zero ...
Instead of using ONFI NAND, a non-ONFI NAND can be used. Note that when selecting a specific non-ONFI NAND, the Read ID and Geometry of the NAND should be compared to the supported configurations documented in the device Technical Reference Manual. DRA72x SR 2.0, 1.0 DRA71x SR 2.0 DR...
