  • Patent number: 11521979
    Abstract: Methods, systems, and devices for power gating in a memory device are described for using one or more memory cells as drivers for load circuits of a memory device. A group of memory cells of the memory device may represent memory cells that include a switching component and that omit a memory storage element. These memory cells may be coupled with respective plate lines that may be coupled with a voltage source having a first supply voltage. Each memory cell of the group may also be coupled with a respective digit line that may be coupled with the load circuits. Respective switching components of the group of memory cells may therefore act as drivers to apply the first supply voltage to one or more load circuits by coupling a digit line with a plate line having the first supply voltage.

  • Patent number: 11150909
    Abstract: In an approach for decreasing a rate of logic voltage level transitions in a multiplexor, one of a plurality of inputs to a multiplexor is selected with a first multiplexor select value at a first clock, wherein each input to the multiplexor is identified as one of i) valid and ii) invalid and the first multiplexor select value is latched in a latch until the first multiplexor select value is replaced by a second multiplexor select value. The second multiplexor select value is determined. The second multiplexor select value is applied to the multiplexor at a second clock if and only if the second multiplexor select value is different from the first multiplexor select value and the second multiplexor select value selects a valid input, wherein the second clock follows the first clock. Subsequent to applying the second multiplexor select value, the second multiplexor value is latched in the latch.

  • Patent number: 10331365
    Abstract: A removable non-volatile memory device durably stores a serial number or identifier, which is used to mark multimedia content legally stored on the removable non-volatile memory device. In order to retrieve the serial number, a host electronic system coupled to the removable non-volatile memory device sends a sequence of multiple file access commands to access a predefined target file stored on the removable non-volatile memory device. In accordance with the executed predefined sequence of multiple file access commands, a corresponding sequence of data access commands are received at the removable non-volatile memory device and are interpreted as a request by the host electronic device to read the serial number. The removable non-volatile memory device outputs the serial number in response to the sequence of data access commands.

  • Patent number: 8638886
    Abstract: A parallel implementation of the Viterbi decoder becomes more efficient when it employs end-state information passing as disclosed herein. The improved efficiency enables the usage of less area and/or provides the capacity to handle higher data rates within a given heat budget. In at least some embodiments, a decoder chip employs multiple decoders that operate in parallel on a stream of overlapping data blocks, using add-compare-select operations, to obtain a sequence of state metrics representing a most likely path to each state. Each decoder passes information indicative of a selected end-state for a decoder operating on a preceding data block. Each decoder in turn receives, from a decoder operating on a subsequent data block, the information indicative of the selected end-state. The end-state information eliminates any need for post-data processing, thereby abbreviating the decoding process.

  • Patent number: 8193832
    Abstract: A system comprises a plurality of requesting agents and granting agents configured in an array of rows and a plurality of columns. Corresponding to each requesting agent is a plurality of row address decoders and column address decoders, one row decoder for each row of granting agents and one column decoder for each column of granting agents. Each row decoder receives a first subset of an address' bits from a requesting agent and generates a row output bit provided to each granting agent in the row of that row address decoder. Each column decoder receives a second subset of bits of the address and generates a column output bit provided to each granting agent in the column corresponding to such column decoder. Each granting agent logically combines the row and column output bits from row and column decoders of a requesting agent to generate a request signal for the granting agent.

    Abstract: Logic circuits provide networks to simulate the functions of neural networks of the brain, and can discriminate degrees of state, and combinations of degrees of state, corresponding to a number of neurons. Logic circuits comprise Recursive AND NOT Conjunctions (RANCs), or AND NOT gates. A RANC is a general logic circuit that performs conjunctions for 2n possible combinations of truth values of n propositions. The RANCs function dynamically, with capabilities of excitation and inhibition. Networks of RANCs are capable of subserving a variety of brain functions, including creative and analytical thought processes. A complete n-RANC produces all conjunctions corresponding to the 2n possible combinations of truth values of n propositions.

    Abstract: A system for fast determination of a horizontal minimum of multiple digital values including a difference circuit and a compare circuit. The difference circuit may include first and second adders in which the first adder compares upper bits of a first digital value with upper bits of a second digital value and provides a first carry output and a propagate output. The second adder compares lower bits of the first digital value with lower bits of the second digital value and provides a second carry output. The compare circuit determines whether the first digital value is greater than the second digital value based on the carry and propagate outputs. Multiple difference circuits may be used to compare each of multiple digital values with every other digital value to provide corresponding compare bits, which are then used to determine a minimum one of the digital values and its corresponding location.

  • Patent number: 7872502
    Abstract: One embodiment of the present invention is a method for constructing defect-and-failure-tolerant demultiplexers. This method is applicable to nanoscale, microscale, or larger-scale demultiplexer circuits. Demultiplexer circuits can be viewed as a set of AND gates, each including a reversibly switchable interconnection between a number of address lines, or address-line-derived signal lines, and an output signal line. Each reversibly switchable interconnection includes one or more reversibly switchable elements. In certain demultiplexer embodiments, NMOS and/or PMOS transistors are employed as reversibly switchable elements. In the method that represents one embodiment of the present invention, two or more serially connected transistors are employed in each reversibly switchable interconnection, so that short defects in up to one less than the number of serially interconnected transistors does not lead to failure of the reversibly switchable interconnection.
