  • Patent number: 9292076
    Abstract: Fast recalibration circuitry for input/output (IO) compensation finite state machine power-down exit is described. The fast recalibration circuitry includes a finite state machine having a volatile memory to store an IO compensation setting and a power supply coupled to the volatile memory to provide power to the volatile memory. The fast recalibration circuitry includes a persistent memory coupled to the volatile memory and one or more circuits, coupled to the volatile memory and the persistent memory, to identify an event to enter a power-down mode, wherein the power-down mode comprises the power supply removing power from the volatile memory and transfer the IO compensation setting in the volatile memory to the persistent memory prior to the power supply removing the power from the volatile memory.

  • Patent number: 6940778
    Abstract: An embodiment of the invention provides a circuit for reducing power in memory cells. The input of the circuit is connected to the wordline of the memory cells. When the wordline is active, the output of the circuit applies a voltage near VDD to the positive voltage supply node of the memory cells. When the wordline is inactive, the output of the circuit applies a voltage that is reduced by at least one Vt from VDD to the positive voltage supply node of the memory cells.

  • Patent number: 6580635
    Abstract: During read operations of a column of RAM cells, a bitline is electrically broken into two sections. This reduces the capacitance that needs to be discharged by the RAM cell itself. A buffer is used during the read operation to relay data from one part of the split bitline to the other. A weak pullup path is also provided to hold the non-driven end of the line in a stable condition. During non-read operations, the two sections of bitline are electrically connected.

  • Patent number: 6549060
    Abstract: A dynamic logic multiplexer has pull-ups on its input signals that pull-up the input signals when not selected. This reduces leakage current that may contribute to incorrect switching of the output. The output stage of the multiplexer includes a latched dynamic node followed by two gain stages, and an open-drain output.

  • Patent number: 6301140
    Abstract: A content addressable memory, CAM, cell wherein the only compare-transfer FETS used are NFETs. The gates of the NFET compare-transfer FETS are driven to a voltage above the positive power supply, VDD. By precharging the bitlines to the negative power supply voltage, GND, the gate of one of the compare-transfer NFETS is driven above VDD when a bitline transitions from a “low” value to a “high” value. The capacitance between the bitline being driven high and the gate of a compare-transfer NFET couples the gate higher than VDD. This bootstrapping technique improves the compare access time of a CAM. In addition, this technique reduces the capacitance on the bitlines resulting in faster read and write access times and reduces the physical size of the CAM.
