摘要: A sense amplifier (40) uses a body shorting device (60) to selectively electrically short circuit the bodies of two transistors (44, 48) that function as a differential sensing pair. Equalization of charge injected into the bodies functions to minimize offset voltage between the two bodies. The body shorting device selectively shorts the bodies in response to a body control signal after a sense operation and after asserting a precharging signal to initiate precharging of the sense amplifier's outputs.

摘要: In accordance with at least one embodiment, column level power control granularity is provided to control a low power state of a memory using a drowsy column control bit to control the low power state at an individual column level to protect the memory from weak bit failure. In accordance with at least one embodiment, a method of using a dedicated row of bit cells in a memory array is provided wherein each bit in the row controls the low power state of a respective column in the array. A special control signal is used to access the word line, and the word line is outside of the regular word line address space. A mechanism is provided to designate the weak bit column and set the control bit corresponding to that particular column to disable the drowsy/low power state for that column.

摘要: A circuit (50) that receives dynamic signals performs both logic and latching to achieve high speed operation. The circuit has a clock that defines both an evaluation phase and a precharge phase in which the dynamic signals are evaluated during the evaluation phase. The circuit (50) functions by precharging a latch node (INT) during the evaluation phase then performing evaluation as well during the evaluation phase. The evaluation results in providing a valid logic state to the latch node. A latch circuit (54) latches this valid state during the precharge phase and holds it in this valid state during the precharge phase. This can be adapted to select which one of the dynamic signals is to be coupled and latched on the latch node (INT).

摘要: A memory device (28) executes memory access operations of two or more storage locations concurrently. The memory device (28) is comprised of a plurality of memory bank decode logic circuits (30, 32, 56) and a plurality of memory banks (34, 52). Each of the decode logic circuits decodes a first information and control signal set to enable a first memory bank to begin and complete a memory access operation. Each memory bank is comprised of a plurality of latch circuits (39,40, 42, 50) to store a predetermined information and control signal set necessary to perform the memory access operation. A second control signal and information set may, therefore, enable a second memory bank within the memory device (28) to perform a second memory access operation concurrently in time with the first memory access operation.

摘要: In a static random access memory in which the array is comprised of MOS transistors and at least some of the peripheral circuits are comprised of bipolar transistors, the bit lines and data lines are precharged to a base to emitter voltage drop (i.e. one Vbe) below the positive power supply voltage. This increases cell stability. Additionally, Vbe varies comparatively little over process. Additionally, precharging the bit lines and data lines to a Vbe below the positive power supply voltage allows for the use of a high speed bipolar differential amplifier in its optimum operating range as the first stage sense amplifier.

摘要: A circuit for determining a threshold indication of temperature with respect to a threshold temperature. The circuit includes a timer circuit and a temperature sensor circuit having an counter whose output has a relationship to temperature. At the end of a period determined by the timer circuit, a comparator circuit compares the count of the counter with an indication of the threshold temperature to determine a state of the threshold indication. In response to a change in state of the threshold indication, the circuit changes one of the count time or the counter output's relationship to temperature to provide a hysteresis for the threshold indication.
