A low power sequential circuit (e.g., latch) uses a non-linear polar capacitor to retain charge with fewer transistors than traditional CMOS sequential circuits. In one example, a sequential circuit includes pass-gates and inverters, but without a feedback mechanism or memory element. In another example, a sequential uses load capacitors (e.g., capacitors coupled to a storage node and a reference supply). The load capacitors are implemented using ferroelectric material, paraelectric material, or linear dielectric. In one example, a sequential uses minority, majority, or threshold gates with ferroelectric or paraelectric capacitors. In one example, a sequential circuit uses minority, majority, or threshold gates configured as NAND gates.

A method for providing a high-speed data communication between a host and field-programmable gate array (“FPGA”) is disclosed. The method, in one embodiment, is capable of identifying a data rate on a bus containing a P-channel and an N-channel operable to transmit signals in accordance with a high-speed Universal Serial Bus (“USB”) protocol. Upon sampling, by a first input deserializer, first two samples of data signals carried by the P-channel in accordance with a first clock signals clocking twice as fast as the data rate of the P-channel, a second input deserializer is used to sample the second two samples of data signals transmitted by the N-channel in accordance with a second clock signal running twice as fast as the data rate of the N-channel with a ninety (90) degree phase shift. The method subsequently forwards the data signals to one or more configurable logic blocks (“LBs”) in FPGA.

A power terminal of a die functional module within the die is connected to a connection point lead-out terminal through a silicon stack connection point. A power gating circuit is arranged within the silicon connection layer. A power output terminal of the power gating circuit within the silicon connection layer is connected to the corresponding connection point lead-out terminal of the die and thus connected to the power terminal of the die function module, so that the power gate circuit can control power supply to the die function module according to an obtained sleep control signal, and the idle die function module can enter into a sleep state to save power.

A method may include determining whether the topology of a network includes a direct path between a first endpoint and a second endpoint in the network. A direct path may be used to send a first type of traffic from the first endpoint to the second endpoint whereas any currently available path may be used to send a second type of traffic from the first endpoint to the second endpoint. If the topology of the network does not include a direct path, the first type of traffic may be buffered at the first endpoint until the topology of the network is reconfigured to include the direct path. The topology of the network may be reconfigured when at least one switch in the network reconfigures, for example, by switching from one interconnection to another interconnection pattern. Related systems and articles of manufacture are also provided.

A memory system includes a nonvolatile memory, and a controller including an equalizer circuit and a clock-and-data output circuit. The equalizer circuit receives a first data signal from a host via a serial communication, reduces an inter-symbol interference jitter of the first data signal to generate a second data signal, and outputs the second data signal. The clock-and-data output circuit extracts a third data signal and a clock signal from the second data signal and outputs the third data signal and the clock signal. The controller executes, when a link speed with the host is switched, a process of detecting predetermined data in the third data signal based on the first data signal received from the host, and resets a state of the clock-and-data output circuit when the predetermined data is not detected within a predetermined period of time.

An integrated circuit that includes very large adder circuitry is provided. The very large adder circuitry receives more than two inputs each of which has hundreds or thousands of bits. The very large adder circuitry includes multiple adder nodes arranged in a tree-like network. The adder nodes divide the input operands into segments, computes the sum for each segment, and computes the carry for each segment independently from the segment sums. The carries at each level in the tree are accumulated using population counters. After the last node in the tree, the segment sums can then be combined with the carries to determine the final sum output. An adder tree network implemented in this way asymptotically approaches the area and performance latency as an adder network that uses infinite speed ripple carry adders.
