Abstract: Methods, systems, and devices for storing and reading data at a memory device are described. A memory device may utilize one or more storage states to store data within a data word. The memory device may exhibit higher data leakage or more power consumption when storing or reading a first storage state compared to storing or reading one or more other storage states. In some cases, the memory device may generate a second data word corresponding to a first data word by modifying each symbol type of the first data word to generate a different symbol type for the second data word. A memory device may reduce the occurrence of a storage state associated with large data leakage, or high-power consumption, or both. Further, the memory device may generate and store an indicator indicating the transformation of a corresponding data word.

Abstract: Some embodiments include apparatus, systems, and methods having a base, a first die, a second arranged in a stacked with the first die and the base, and a structure located in the stack and outside at least one of the first and second dice and configured to transfer signals between the base and at least one of the first and second dice.

Abstract: Embodiments of the disclosure are drawn to apparatuses and methods for repairing multiple bit lines with a same column select value. A memory mat may be bordered by a first gap and a second gap. Each gap includes sets of sense amplifiers and a redundant sense amplifier set. The sense amplifier sets are activated by an enable signal and share a column select (CS) signal in common. The redundant sense amplifier set is activated by a redundant enable signal separate from the enable signal. In some embodiments, the redundant sense amplifier sets are coupled to a redundant CS signal which is separate from the CS signal.

Abstract: Systems, methods and apparatus to read target memory cells having an associated reference memory cell configured to be representative of drift or changes in the threshold voltages of the target memory cells. The reference cell is programmed to a predetermined threshold level when the target cells are programmed to store data. In response to a command to read the target memory cells, estimation of a drift of the threshold voltage of the reference is performed in parallel with applying an initial voltage pulse to read the target cells. Based on a result of the drift estimation, voltage pulses used to read the target cells can be modified and/or added to account for the drift estimated using the reference cell.

Abstract: Techniques are provided for writing a high-level state to a memory cell capable of storing three or more logic states. After a sense operation performed by a first sense component and a second sense component, a digit line may be isolated from the first sense component and the second sense component. The high-level state may be stored in the memory cell, then a second state may be stored in the memory cell, in which the second state may be a mid-level state or a low-level state. The second state may be stored based on a write-back component identifying that the second state was stored in the memory cell before the write back procedure.

Abstract: Techniques are provided for sensing a signal associated with a memory cell capable of storing three or more logic states. To sense the memory cell (e.g., a signal associated with the memory cell), a charge may be transferred between a digit line and a node coupled with a plurality of sense components using a charge transfer device. Once the charge is transferred, at least some if not each of the plurality of sense components may sense the charge using one of a variety of sensing schemes. For example, the charge may be sensed by each sense component at a same time using a single fixed reference value, or at different times using different fixed reference values. Based on the charge being transferred or transferred with the node (e.g., using the charge transfer device) and each sense component sensing the charge, a logic state associated with the memory cell may be determined.

Abstract: Techniques are provided for reading a memory cell capable of storing three or more logic states. To read the memory cell, a charge may be transferred between a digit line and a sense component using a charge transfer device. The charge may be transferred by biasing a gate of the charge transfer device to a first voltage and discharging the memory cell onto the digit line, which may result in the digit line being biased to a second voltage. Based on whether the second voltage exceeds the first voltage, the charge transfer device may transfer the charge associated with the memory cell (e.g., and discharged onto the digit line) to the sense component. A charge may be transferred from a memory cell to a sense component based on a value of the logic state stored to the memory cell.

Abstract: Devices and methods for a sensing scheme are described. A device may include a memory array and a column select line configured to couple with a single page of a set of pages within the memory array when the single page is selected during an access operation. The column select line may be isolated from other pages (e.g., unselected pages) of the set. The device may include a set of sense component groups coupled with the single page. Each sense component group of the set may be configured to access one or more memory cells of the single page using the column select line. The device may include a decoding component configured to couple a sense component group of the set with an I/O line of an I/O channel. The device may communicate information with the I/O line during the access operation.
