An adjustable voltage regulator circuit, including a voltage conversion circuit, a voltage conversion controller, and a clock generator, is provided. The voltage conversion circuit receives an input voltage to generate an output voltage. The voltage conversion controller detects the output voltage, compares the output voltage with a reference voltage value, and outputs an enable signal based on a comparison result to control the voltage conversion circuit to adjust the output voltage. The clock generator generates a first clock signal and a second clock signal to respectively drive the voltage conversion circuit and the voltage conversion controller. The voltage conversion controller adjusts the enable signal to gradually adjust the output voltage to a predetermined voltage range.

A computing-in-memory circuitry includes multiple digital-to-analog converters, multiple computing arrays, and multiple charge processing networks. The digital-to-analog converters convert external data into input data and the digital-to-analog converters are connected in series with a corresponding plurality of output capacitor pairs. The computing arrays receive the input data from both ends and execute a computation to output a first computing value. The charge processing networks receive and accumulate the first computing values over a predetermined time interval through switching pairs in series with the output capacitor pairs. The charge processing networks evenly distribute charges of the first computing value to selected output capacitor pairs and compare voltage differences between two ends of the output capacitor pairs to output a second computing value.

The present disclosure illustrates a ternary content addressable memory (TCAM) device for software defined networking and method thereof. In the TCAM device, M bits of each forwarding rule is stored as a first part into a NAND-Type TCAM, and N bits of the same forwarding rule is stored as a second part into a NOR-Type TCAM. M bits of searching data is compared with the first part to generate a first matching result, N bits of the searching data is compared with the second part to generate a second matching result when the first matching result indicates match, and comparing process for the second part is disabled when the first matching result indicates mismatch. The mechanism is help to improve flexibility of the TCAM in words length and to reduce power consumption.
