  • Publication number: 20240118826
    Abstract: A memory device includes at least one bitcell coupled to a local bitline. The at least one bitcell includes multiple sets of a plurality of transistor devices. The first set of the plurality of transistor devices is configured to form a single write (1W) port for receiving digital data. The second set of the plurality of transistor devices is configured as an inverter pair. The inverter pair stores the digital data. The third set of the plurality of transistor devices is configured to form a single read (1R) port. The 1R port can be used to access the digital data stored at the inverter pair and output the digital data on the local bitline. The plurality of transistor devices includes an equal number of P-channel transistor devices and N-channel transistor devices.

  • Publication number: 20230170012
    Abstract: Embodiments herein relate to circuitry which allows data to be processed and written back within an SRAM device. In a toggle operation, a memory cell is read and the bit at the complementary output node of a sense amplifier is written back to the memory cell. In a copy operation, a memory cell is read and the bit at the primary output node of the sense amplifier is written to another memory cell in the column. In another aspect, logic operations such as AND, OR, majority, AND-OR, OR-AND, and associated inverse operations can be performed within the SRAM device. This can involve writing data to one or more control memory cells in the same column as the data memory cells involved in the logic operation, and setting the respective word lines to be active concurrently.

  • Publication number: 20160379706
    Abstract: Memory with asymmetric power delivery for keeper cells in the memory are provided. In some embodiments, first and second power delivery circuits use separate first and second independently regulated power supplies. The first supply may be a supply nominally used for the memory structure, while the second supply may be lower than the first supply. In some embodiments, during a write operation, the first (higher) supply is used for one of the logic elements in a keeper cell, while the second (lower) supply is used for the other keeper logic element.

  • Patent number: 9059715
    Abstract: Methods and systems to implement voltage level shifting with interim-voltage-controlled contention-interruption. A voltage level shifter (VLS) may include voltage level shift circuitry to level shift an input logical state from an input voltage swing to an output voltage swing. The VLS may include contention circuitry, a contention interrupter, and an interrupt controller to generate a contention-interrupt control having an interim voltage swing. A lower limit of the interim voltage swing may correspond to a lower limit of the output voltage swing. An upper limit of the interim voltage swing may correspond to an upper limit of the input voltage swing. The VLS may be implemented to level shift true and complimentary logical states, such as with cascode voltage switch logic (CVSL).

  • Patent number: 8068371
    Abstract: Methods and systems to dynamically control state-retention strengths of a plurality of memory cells during a write operation to a subset of the memory cells. Dynamic control may include weakening state-retention strengths of the plurality of memory cells during a write operation to a subset of the memory cells, while preserving state-retention abilities of remaining ones of the plurality of memory cells. Weakening may include adjusting one or more resistances between one or more power supplies and the plurality of memory cells. Dynamic control may be selectively performed on portions of each of the memory cells in response to an input data logic state. Dynamic control may reduce a write contention within the subset of memory cells without disabling state-retention abilities of remaining ones of the plurality of memory cells, and may improve write response times of the memory cells.
