Samsung patents a faster circuit for storing digital data

Samsung has been granted a patent for a specific type of electronic component called a toggle flip-flop. This component uses a unique arrangement of circuits to switch its output state in sync with a clock signal, which is the basic rhythm of a computer chip. The design includes a specific mechanism to reset the internal data signal independently of other parts to ensure accurate switching.

Why it mattersThis is a low-level hardware improvement that helps engineers build more reliable and efficient microprocessors, though it is unlikely to be noticed by end-users directly.

In the filing’s own words

A flip-flop configured to generate an output toggling according to an input clock includes an inverter configured to generate the output by inverting a first data signal, a first circuit configured to generate a second data signal based on an input clock and a latch signal, a second circuit configured to generate the latch signal based on the input clock and the second data signal, and a third circuit configured to generate the first data signal using the input clock, the second data signal, and the latch signal, wherein the third circuit is further configured to pull down the first data signal, independently of the second data signal, using the input clock and the latch signal.

What exactly they claim (claim 1)

1. A flip-flop configured to generate an output toggling according to an input clock, the flip-flop comprising: an inverter configured to generate the output by inverting a first data signal; a first circuit configured to generate a second data signal based on the input clock, the first data signal, and a latch signal; a second circuit configured to generate the latch signal based on the input clock and the second data signal; and a third circuit configured to generate the first data signal using the input clock, the second data signal, and the latch signal, wherein the third circuit is further configured to pull down the first data signal, independently of the second data signal, using the input clock and the latch signal.
