    Abstract: Disclosed is a memory structure that includes wordlines (WL) and cell supply lines (CSL) positioned between and parallel to voltage boost lines (VBLs). The VBLs enable capacitive coupling-based voltage boosting of the adjacent WL and/or CSL depending on whether a read or write assist is required. During a read operation, all VBLs for a selected row can be charged to create coupling capacitances with the WL and with the CSL and thereby boost both the wordline voltage (Vwl) and the cell supply voltage (Vcs) for a read assist. During a write operation, one VBL adjacent to the WL for a selected row can be charged to create a coupling capacitance with the WL only and thereby boost the Vwl for a write assist. The coupling capacitances created by charging VBLs in the structure is self-adjusting in that as the length of the rows increase so do the potential coupling capacitances.

The first memory module includes one or more memory ranks of memory devices, and a first plurality of thermal sensors. The second memory module includes one or more memory ranks of memory devices, and a second plurality of thermal sensors. The central processing unit receives first thermal telemetry data for the first memory module from the first thermal sensors, and second thermal telemetry data for the second memory module from the second thermal sensors. In response to the reception of the first thermal telemetry data, the central processing unit determines a first localized temperature of a first memory rank. In response to the first localized temperature exceeding a threshold temperature, the central processing unit re-maps access of data from the first memory rank to a second memory rank.

  • Patent number: 11740964
    Abstract: Methods, systems, and devices for performing an error correction operation using a direct-input column redundancy scheme are described. A device that has read data from data planes may replace data from one of the planes with redundancy data from a data plane storing redundancy data. The device may then provide the redundancy data to an error correction circuit coupled with the data plane that stored the redundancy data. The error correction circuit may operate on the redundancy data and transfer the result of the operation to select components in a connected error correction circuit. The components to which the output is transferred may be selected based on data plane replaced by the redundancy data. The device may generate syndrome bits for the read data by performing additional operations on the outputs of the error correction circuit.

    Abstract: Devices and techniques are disclosed herein for more efficiently exchanging large amounts of data between a host and a flash storage system. In an example, read commands or write commands can optionally include a file-type indicator. The file-type indicator can allow for exchange of data between the host and the flash storage system using a single record of a Flash Translation Layer (FTL) table or logical-to-physical (L2P) table, and where the amount of data can be much larger than the atomic unit associated with the flash storage system.

  • Patent number: 11705904
    Abstract: A microcontroller includes an input pin and internal pull-up and pull-down circuits. External pull-up and pull-down circuits are also coupled to the input pin. The microcontroller is operable according to different configuration modes which include configuring the input pin in a floating state. A control logic then configures the internal pull-up and pull-down circuits according to an internal pull-up mode to acquire a first input voltage signal (at a first logic value) from the input pin, and further configure the internal pull-up and pull-down circuits according to an internal pull-down mode to acquire a second input voltage signal (at a second logic value) from the input pin. A selection of the operating mode of the MCU is then made based on the acquired first and second logic values.

The bulk voltage control circuit independently provides a bulk voltage to the bulk electrode. A last-stage buffer of the buffer circuit is also activated by the bulk voltage to control the pass transistor during the reading operation of the electronic fuse circuit. A method for providing power to an electronic fuse circuit is also provided.

    Abstract: Apparatuses and methods for setting a duty cycler adjuster for improving clock duty cycle are disclosed. The duty cycle adjuster may be adjusted by different amounts, at least one smaller than another. Determining when to use the smaller adjustment may be based on duty cycle results. A duty cycle monitor may have an offset. A duty cycle code for the duty cycle adjuster may be set to an intermediate value of a duty cycle monitor offset. The duty cycle monitor offset may be determined by identifying duty cycle codes for an upper and for a lower boundary of the duty cycle monitor offset.

  • Patent number: 11664074
    Abstract: Systems, methods and apparatus to program memory cells to an intermediate state. A first voltage pulse is applied in a first polarity across each respective memory cell among the memory cells to move its threshold voltage in the first polarity to a first voltage region representative of a first value. A second voltage pulse is then applied in a second polarity to further move its threshold voltage in the first polarity to a second voltage region representative of a second value and the intermediate state. A magnitude of the second voltage pulse applied for the memory cells is controlled by increasing the magnitude in increments until the memory cells are sensed to be conductive. Optionally, prior to the first voltage pulse, a third voltage pulse is applied in the second polarity to cancel or reduce a drift in threshold voltages of the respective memory cell.

  • Patent number: 11610612
    Abstract: A row decoder includes decoder logic generating an initial word line signal, and two inverters. The first inverter is formed by a first p-channel transistor having a source coupled to a supply voltage and a gate receiving the initial word line signal. The second inverter is formed by a first n-channel transistor having a drain coupled to a drain of the first p-channel transistor, a source coupled to a shared ground line, and a gate receiving the initial word line signal. An inverse word line signal is generated at the drain of the first n-channel transistor. A second inverter inverts the inverse word line signal to produce a word line signal. Negative bias generation circuitry generates a negative bias voltage on the shared ground line when the initial word line signal is logic high, and otherwise couples the shared ground line to ground.
