摘要： Techniques are provided for a register file cell that includes a primary storage portion configured to store a first value, and a secondary storage portion that is coupled to the primary storage portion. The secondary storage portion is configured to function as a scan latch during a test operation, and is further configured to store a second value during normal operation. The second value is a duplicate of the first value. The cell further includes an error detection portion that is coupled to the primary storage portion and the secondary storage portion and is configured to indicate a difference between the first value and the second value, caused by a soft error.

摘要： A register file is often used within integrated circuitry to temporarily hold data. Sometimes this data needs to be retained within the register file for a period of time, such as when there is a stall operation. Conventional register files have utilized a hold multiplexor to perform such a stall operation. The multiplexor however inserts a delay that is undesirable in high performance integrated circuitry. The multiplexor is replaced with a tri-state inverter coupled to the global bit line of the register file, which minimizes this additional delay from the register file data access time.

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.

摘要： A method and apparatus is effective to preserve logic state potential levels in logic circuitry notwithstanding alpha particle collisions. Cross-coupled circuitry, including active devices, are implemented in a complementary logic circuit arrangement to hold current logic values in the event of a premature switching such as a switching that may be induced by alpha particle collision with the semiconductor logic circuit. Stabilizing transistor switching devices are arranged to sense an inappropriate or premature switching initiation and respond thereto by operating to maintain the appropriate logic levels within the logic circuitry. In one embodiment, the internal node of an upper circuit in a dual-rail logic circuit is connected to a gate terminal of a cross-coupled PFET device in the lower circuit. The cross-coupled PFET device is operable to sense an initiated untimely switching action in the upper circuit and effect a re-application of the holding PFET in the upper circuit to re-establish the appropriate logic potential levels in the upper circuit.

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： In one form of the invention, a radiation resistant latch has an overall output node, and first, second and third sublatches. The sublatches each have input circuitry, an output node coupled to the sublatch's 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 responsively generate binary-state output signals on their respective output nodes. The first and second sublatches are coupled to the third sublatch and the third sublatch has its output signal coupled to the overall output node such that if any one of the three sublatches is subjected to a radiation induced erroneous change of state, the output signals of the other two sublatches reduce an effect of the third sublatch feedback circuitry on an overall output signal for the latch.
