  • Patent number: 9336837
    Abstract: A low voltage sensing scheme reduces active power down standby leakage current in a memory device. A clamping device or diode is used between a Psense amplifier control line (e.g. ACT) and Vcc and/or between an Nsense amplifier control line (e.g. RNL*) and Vss (ground potential). The clamping diode is not enabled during normal memory operations, but is turned on during active power down mode to reduce leakage current through ACT and/or RNL* nodes. The clamping device connected to the ACT node may reduce the voltage on the ACT line during power down mode, whereas the clamping device connected to the RNL* node may increase the voltage on the RNL* line during power down mode to reduce sense amplifier leakage current through these nodes. Because of the rules governing abstracts, this abstract should not be used to construe the claims.

    Abstract: Devices and methods that allow dynamic management of throughput in a memory device based on a power supply voltage are provided. According to various embodiments, the power supply level can be monitored. Based on the result of the monitoring, an appropriate throughput can be determined. Once the appropriate throughput is determined, an appropriate control signal based on the determined throughput can be generated. The control signal can be configured to cause a bitline driver circuit in a memory array to activate a number of bitlines consistent with the determined throughput.

  • Patent number: 9171608
    Abstract: A three-dimensional (3D) memory cell separation among 3D integrated circuit (IC) (3DIC) tiers is disclosed. Related 3DICs, 3DIC processor cores, and methods are also disclosed. In embodiments disclosed herein, memory read access ports of a memory block are separated from a memory cell in different tiers of a 3DIC. 3DICs achieve higher device packing density, lower interconnect delays, and lower costs. In this manner, different supply voltages can be provided for the read access ports and the memory cell to be able to lower supply voltage for the read access ports. Static noise margins and read/write noise margins in the memory cell may be provided as a result. Providing multiple power supply rails inside a non-separated memory block that increases area can also be avoided.

  • Patent number: 9166596
    Abstract: Integrated circuits may include memory interface circuitry that communicates with memory. The memory interface circuitry may include latch circuitry that receives a data strobe enable signal from the memory controller and latches the data strobe enable signal using a data strobe signal received from the memory. The integrated circuit may include logic circuitry that gates the data strobe signal using the latched data strobe enable signal. The logic circuitry may pass the data strobe signal in response to activation of the latched data strobe enable signal. The integrated circuit may include counter circuitry that monitors the gated data strobe signal. The counter circuitry may monitor the gated data strobe signal by counting pulses in the gated data strobe signal to produce a counter value. When the counter value reaches a target value, the logic circuitry may block the data strobe signal from passing to the memory controller.

  • Patent number: 9142266
    Abstract: Within a memory 2 comprising an array 4 of bit cells 6 write driver circuitry 14 uses a boosted write signal which is boosted to a lower than normal level during a write operation. Column select transistors 16 are driven by column select circuitry 12. The column select signal is boosted to a lower than normal level when a column is unselected and to higher than a normal level when a column is selected. Voltage boost circuitry, such as charge pumps 20, 22 are employed within the column select circuitry 12 to achieve these boosted levels for the columns select signal.

  • Patent number: 9134779
    Abstract: A method, circuit arrangement, and program product for dynamically reallocating power consumption at a component level of a processor. Power tokens representative of a power consumption metric are allocated to interconnected IP blocks of the processor, and as additional power is required by an IP block to perform assigned operations, the IP block may communicate a request for additional power tokens to one or more interconnected IP blocks. The interconnected IP blocks may grant power tokens for the request based on a priority, availability, and/or power consumption target. The requesting IP block may modify power consumption based on power tokens granted by interconnected IP blocks for the request. A power management block may adjust power token allocation of one or more IP blocks by communicating a command to one or more IP blocks and/or by adjusting a power token request.
