Abstract: Methods, systems, and devices for multiple transistor architecture for three-dimensional memory arrays are described. A memory device may include conductive pillars coupled with an access line using two transistors positioned between the conductive pillar and the access line. As part of an access operation for a memory cell coupled with the conductive pillar, the memory device may be configured to bias the access line to a first voltage and activate the two transistors using a second voltage to couple the conductive pillar with the access line. Additionally, the memory device may be configured to bias a gate of a first transistor and a gate of a second transistor coupling an unselected conductive pillar with the access line to a third and fourth voltage, respectively, which may deactivate at least one of the first or second transistor during the access operation and isolate the unselected conductive pillar from the access line.

Abstract: A method includes setting a current level of a write signal to a first non-zero value for a first period of time. The write signal is provided to a memory element during the first period of time. The current level of the write signal is adjusted from the first non-zero value to a second non-zero value, different from the first non-zero value, for a second period of time. The write signal is provided to the memory element during the second period of time. The current level of the write signal is adjusted from the second non-zero value to a third value, different from the first non-zero value and different from the second non-zero value, for a third period of time. The write signal is provided to the memory element during the third period of time.

Abstract: Methods, systems, and devices for cross point array architecture for multiple decks are described. A memory array may include multiple decks, such as six or eight decks. The memory array may also include sockets for coupling access lines with associated decoders. The sockets may be included in sub-blocks of the array. A sub-block may be configured to include sockets for multiple access lines. A socket may intersect an access line in the middle of the access line, or at an end of the access line. Sub-blocks containing sockets for an access line may be separated by a period based on the access line.

Abstract: The embodiments herein describe technologies of initializing resistive memory devices (e.g., non-volatile and volatile memory devices). In one method, a first voltage is applied across a resistance change material of a memory cell to form an initial filament and multiple cycles are performed to condition the initial filament. Each of the multiple cycles includes: applying a second voltage with a first polarity across the resistance change material; and applying a third voltage with a second polarity across the resistance change material.

Abstract: Disclosed herein are related to a memory array. In one aspect, the memory array includes a set of resistive storage circuits including a first subset of resistive storage circuits connected between a first local line and a second local line in parallel. The first local line and the second local line may extend along a first direction. In one aspect, for each resistive storage circuit of the first subset of resistive storage circuits, current injected at a first common entry point of the first local line exits through a first common exit point of the second local line, such that each resistive storage circuit of the first subset of resistive storage circuits may have same or substantial equal resistive loading.

Abstract: An IMC circuit includes a memory cells arranged in matrix. Computational weights for an IMC operation are stored in groups of cells. Each row of groups of cells includes a positive and negative word linen. Each column of groups of cells includes a bit line. The IMC operation includes a first elaboration where a word line signal is applied to the positive/negative word line of the group of cells depending on the positive/negative sign, respectively, of the coefficient data, with a positive MAC output on the bit line. In a second elaboration, a word line signal is applied to the negative/positive word line of the group of cells depending on the positive/negative sign, respectively, of the coefficient data, with a negative MAC output on the bit line. The IMC operation result is obtained from a difference between the positive and negative MAC operations.

Abstract: Systems and methods for performing a pattern matching operation in a memory device are disclosed. The memory device may include a controller and memory arrays where the memory arrays store different patterns along bit lines. An input pattern is applied to the memory array(s) to determine whether the pattern is stored in the memory device. Word lines may be activated in series or in parallel to search for patterns within the memory array. The memory array may include memory cells that store binary digits, discrete values or analog values.
