Abstract: Methods, systems, and devices for access heatmap generation at a memory device are described. In some examples, a memory device may maintain a register for tracking access operation occurrence, for which access operations of an address of the memory device may be mapped to multiple fields of the register. In some cases, in response to a first access operation performed on a first address of the memory device, the memory device may increment a first field and a second field of the register and, in response to a second access operation performed on a second address of the memory device, the memory device may increment the first field and a third field of the register. In some examples, the memory device may maintain a second register having a set of fields that each indicate a respective address for which an access occurrence satisfies a threshold.

Abstract: A single and dual path light detection and ranging (LiDAR) system can transmit and receive light through a silicon substrate backside of a photonic integrated circuit (PIC). The PIC can be interface with an electrical integrated circuit (EIC) using a front side that connects to the EIC using electrical contacts and a backside that faces away from the EIC. High density coupler elements (e.g., pixels, gratings) can emit and receive infrared light that propagates through the PIC layers and the backside towards objects to detection.

Abstract: Described herein are embodiments of systems and methods for determining remaining useful life (RUL) of an electro-mechanical device. The systems may include a compiler and an external network communicatively connected with the compiler. The compiler determines forecasted reliability of the part, determines actual reliability of the part, divides forecasted reliability by actual reliability to determine forecasted useful operation time, Tx, and subtracts total operation time T from forecasted useful operation time Tx to determine RUL.

Abstract: Methods, systems, and devices for techniques to balance log structured merge trees are described. A computing system may rebalance a tree structure having an ordered set of leaf nodes by splitting or joining leaf nodes of the tree structure. To split a leaf node, the computing system may select a key to evenly partition key and value data stored in the leaf. The computing system may place each key block of the leaf node having keys less than or equal to the selected key in a first new leaf node, and may place each key block of the leaf node having keys greater than the selected key in a second new leaf node. To join leaf nodes of the tree structure, the computing system may place each key block and each value block of the leaf node and the adjacent leaf node in a new leaf node.
