Semiconductor circuit with weighted input signal processing
The granted patent US12046286B1 describes a semiconductor circuit that comprises two strings of device units designed to perform complex computations, particularly in the context of quantum annealing. The first string consists of a first and a second device unit arranged in series, while the second string includes a third and a fourth device unit also in series. Each string is associated with a weight signal (W1 for the first string and W2 for the second string) and specific input signals (A, B, A). The output of the semiconductor circuit is derived from the sum of the output signals from both strings, which can be expressed in various logical forms, including combinations of AND operations and weight signals.
Additionally, the patent outlines an operating method for the semiconductor circuit, detailing how the weight signals and input signals are utilized to compute output string signals. The method emphasizes the summation of these output signals to achieve desired logical results, such as A XNOR B or A AND B, depending on the values of the weight signals. The semiconductor circuit is particularly noted for its application in quantum annealing computing, which involves the use of mathematical models to facilitate complex problem-solving. The claims also specify configurations for the strings, including their parallel connection to bit and source lines, and the potential for using NAND strings as part of the design.
