  • Patent number: 11144483
    Abstract: Apparatuses and methods for writing data to a memory array are disclosed. When data is duplicative across multiple data lines, data may be transferred across a single line of a bus rather than driving the duplicative data across all of the data lines. The data from the single data line may be provided to the write amplifiers of the additional data lines to provide the data from all of the data lines to be written to the memory. In some examples, error correction may be performed on data from the single data line rather than all of the data lines.

  • Patent number: 11127438
    Abstract: The present disclosure generally relates to calibrating the communication with a memory device. To ensure proper calibration, interface training (IFT) needs to occur. IFT involves aligning the sampling point, which is an inflection point, of a clock signal with a data signal. The sampling point of the clock (i.e., the clock edge) needs to be located within the valid window of the data signal. The valid window of the data signal is the time in which the signal is guaranteed to be stable, i.e., after the signal has finished the signal transition time. If the sampling point is aligned with the inflection point of the data signal, then the data signal is not properly aligned. If the sampling point is aligned with the rising or falling edge of the data signal, the data may be obtained, but the data signal is misaligned and is dangerously close to being unreadable.

  • Patent number: 10998047
    Abstract: Systems are methods are provided for implementing an analog content addressable memory (analog CAM), which is particularly structured to allow for an amount of variance (fuzziness) in its search operations. The analog CAM may search for approximate matches with the data stored therein, or matches within a defined variance. Circuitry of the analog CAM may include transistor-source lines that receive search-variance parameters, and/or data lines that receive search-variance parameters explicitly within the search input data. The search-variance parameters may include an upper bound and a lower bound that define a range of values within the allotted amount of fuzziness (e.g., deviation from the stored value). The search-variance parameters may program (using analog approaches) the analog CAM to perform searches having a modifiable restrictiveness that is tuned dynamically, as defined by the input search-variance. Thus, highly efficient hardware for complex applications involving fuzziness are enabled.

  • Patent number: 10990160
    Abstract: A programmable semiconductor integrated circuit fabricated on a single microchip device capable of being selectively programmed to perform one or more logic functions provides a sleep mode using an intermittent power saving logic. The circuit includes configurable logic blocks (“LB”), memory, switch, and sleep controller. While LB can enter a power saving sleep mode (“PSSM”) in accordance with its power supply, the memory stores the configuration information for the LB. The switch is configured to manage the LB power supply based on a configurable sleep signal for facilitating the PSSM. The sleep controller facilitates generation of the configurable sleep signal in response to the signal from a power saving output port associated with the LB.

An example apparatus includes: a first-in first-out circuit including a first latch, a second latch and a logic circuit coupled in series. The first latch receives first data and latches the first data responsive to a first input pointer signal. The second latch receives the latched first data from the first latch and latches the received first data responsive to a second input pointer signal that has a different phase from the first input pointer signal and thus provides a second data. The logic circuit receives the second data and an output pointer signal and further provides an output data responsive to the output pointer signal.
