Ferroelectric or paraelectric memory and logic chiplet with thermal management in a multi-dimensional packaging
A packaging technology to improve performance of an AI processing system resulting in an ultra-high bandwidth system. An IC package is provided which comprises: a substrate; a first die on the substrate, and a second die stacked over the first die. The first die can be a first logic die (e.g., a compute chip, CPU, GPU, etc.) while the second die can be a compute chiplet comprising ferroelectric or paraelectric logic. Both dies can include ferroelectric or paraelectric logic. The ferroelectric/paraelectric logic may include AND gates, OR gates, complex gates, majority, minority, and/or threshold gates, sequential logic, etc. The IC package can be in a 3D or 2.5D configuration that implements logic-on-logic stacking configuration. The 3D or 2.5D packaging configurations have chips or chiplets designed to have time distributed or spatially distributed processing. The logic of chips or chiplets is segregated so that one chip in a 3D or 2.5D stacking arrangement is hot at a time.

Common mode compensation for differential multi-element non-linear polar material based gain memory bit-cell
To compensate switching of a dielectric component of a non-linear polar material based capacitor, an explicit dielectric capacitor is added to a memory bit-cell and controlled by a signal opposite to the signal driven on a plate-line.

Writing scheme for multi-element gain ferroelectric memory bit-cell with plate-lines parallel to a bit-line and with individual switches and control on the plate-lines of the bit-cell
A memory is provided which comprises a capacitor including non-linear polar material. The capacitor may have a first terminal coupled to a node (e.g., a storage node) and a second terminal coupled to a plate-line. The capacitors can be a planar capacitor or non-planar capacitor (also known as pillar capacitor). The memory includes a transistor coupled to the node and a bit-line, wherein the transistor is controllable by a word-line, wherein the plate-line is parallel to the bit-line. The memory includes a refresh circuitry to refresh charge on the capacitor periodically or at a predetermined time. The refresh circuit can utilize one or more of the endurance mechanisms. When the plate-line is parallel to the bit-line, a specific read and write scheme may be used to reduce the disturb voltage for unselected bit-cells. A different scheme is used when the plate-line is parallel to the word-line.

Integrated circuit constructions comprising memory and methods used in the formation of integrated circuitry comprising memory
An integrated circuit construction comprising memory comprises two memory-cell-array regions having a peripheral-circuitry region laterally there-between in a vertical cross-section. The two memory-cell-array regions individually comprise a plurality of capacitors individually comprising a capacitor storage node electrode, a shared capacitor electrode that is shared by the plurality of capacitors, and a capacitor insulator there-between. A laterally-extending insulator structure is about lateral peripheries of the capacitor storage node electrodes and is vertically spaced from a top and a bottom of individual of the capacitor storage node electrodes in the vertical cross-section. The peripheral-circuitry region in the vertical cross-section comprises a pair of elevationally-extending walls comprising a first insulative composition. A second insulative composition different from the first insulative composition is laterally between the pair of walls. The pair of walls individually have a laterally-outer side of the first insulative composition that is directly against a lateral edge of the insulator structure that is in different ones of the two array regions. Other embodiments, including methods, are disclosed.

Top electrode for a memory device and methods of making such a memory device
One illustrative device disclosed herein includes a memory cell positioned in a first opening in at least one layer of insulating material. The memory cell comprises a bottom electrode, a memory state material positioned above the bottom electrode and an internal sidewall spacer positioned within the first opening, wherein the internal sidewall spacer defines a spacer opening. The device also comprises a top electrode positioned within the spacer opening.
Embedded memory with encapsulation layer adjacent to a memory stack
A process integration and patterning flow used to pattern a memory array area for an embedded memory without perturbing a fabricating process for logic circuitries. The fabrication process uses a pocket mask (e.g., a hard mask) to decouple the etching process of a memory array area and non-memory area. Such decoupling allows for a simpler fabrication process with little to no impact on the current fabrication process. The fabrication process may use multiple pocket masks to decouple the etching process of the memory array area and the non-memory area. This fabrication process (using multiple pocket masks) allows to avoid exposure of memory material into a second pocket etch chamber. The process of etching memory material is decoupled from the process of etching an encapsulation material. Examples of embedded memory include dynamic random-access memory and ferroelectric random-access memory.
