    摘要: A logic circuit includes an inverter for generating a complement of an output signal from another logic circuit for input to a dynamic logic circuit. The dynamic logic circuit is capable of receiving both the complement signal and dynamic input signals during both the precharge and evaluate phases of the dynamic logic circuit. The complement signal is permitted to switch from both a low level to a high level and a high level to a low level during such stages with the dynamic logic circuit still capable of correctly evaluating the implemented logical operation of the dynamic logic circuit on the complement signal and the dynamic input signals. A p-channel FET is coupled between the internal precharge node and a voltage reference source where the gate electrode of the p-channel FET device receives the complement signal. Such a configuration eliminates the need for duplicate circuitry necessary to generate the complement signal for use by the dynamic logic circuit and also eliminates the addition of clock skew necessary to prevent potential false switching when using a complement signal generated by simple inversion.

    摘要: According to one form, a latch has an output node and sublatches. The sublatches each have an output node coupled to input circuitry and feedback circuitry coupled to the sublatch's output node for reinforcing an output signal of the sublatch. The sublatches are operable to receive a data signal at their respective input circuitry and to generate output signals on their respective output nodes. At least one sublatch output node is coupled to the latch output node. The output nodes of other ones of the sublatches are connected in the latch such that if any one of the sublatches is subjected to a radiation induced erroneous change of state the output signals of the other sublatches reduce an effect of the change on the latch output signal. The latch also includes a number of scanning-mode control switches coupled to ones of the sublatches for scanning data in or out.

    摘要: A dynamic logic circuit is capable of receiving both dynamic and static input signals during both the precharge and evaluate phases of the logic circuit, and the static input signal is permitted to switch from both a low level to a high level and a high level to a low level during such stages and the logic circuit is still capable of correctly evaluating the implemented logical operation on the static and dynamic input signals. This is performed in CMOS by coupling a PFET between the internal precharge node and a voltage reference source where the gate electrode of the PFET device receives the static input signal.

    摘要: A register file method incorporating read-after-write blocking using detection cells provides improved read access times in high performance register files. One or more detection cells identical to the register file cells and located in the register file array are used to control the read operation in the register file by configuring the detection cells to either alternate value at each write or change to a particular value after a write and then detecting when the write has completed by detecting the state change of an active detection cell. The state change detection can be used to delay the leading edge of a read strobe or may be used in the access control logic to delay generation of a next read strobe. The register file thus provides a scalable design that does not have to be tuned for each application and that tracks over voltage and clock skew variation.

    摘要: A method and memory array for reducing sub-threshold leakage in a memory array. A memory array may include a plurality of rows where each row may include one or more groups of cells. Within each group of cells, each cell may be coupled to a ground path and to a power path. A device, e.g., n-type transistor, p-type transistor, may be coupled to either the ground or power path in each group of cells thereby permitting the passing of the sub-threshold leakage from those cells in that group through the device. Consequently, the sub-threshold leakage in the memory array may be reduced.

    摘要: A dynamic-static logical control element for signaling an interval between the end of a control signal and a logical evaluation provides a compact circuit for blocking the indication of a non-evaluated state of a dynamic logic gate until a control signal has ended. The control signal is connected to a precharge input of the control element and a summing node is connected to one or more evaluation trees and to the control element output via an inverter. The inverter is connected to an override circuit that forces the output of the control element to a state opposite the precharge state until the control signal has ended. The output of the control element then assumes a state corresponding to the precharge state until an evaluation occurs. The control element output thus produces a window signal indicating the interval between the end of the control signal and the evaluation.
