  • Patent number: 12278172
    Abstract: In order to relieve the stress on the substrates in a 3D stacked electronic assembly, a substrate frame is divided into a plurality of frame sections that are separated by spaces between the frame sections. These separations allow the substrates to expand/contract in response to temperature variations and other environmental conditions, and generally allow the substrates to move in one or more axial directions. The separations between the substrate portions are design-specific for each substrate design. The placement of IC packages on either side of the substrate is analyzed to identify areas of maximal warpage through physical measurements, physical model simulations, or using a trained neural network. The spaces in the substrate frame are then be placed next to or aligned with the areas of maximal warpage to reduce the stress on the substrate.

  • Patent number: 12277978
    Abstract: A memory system configured to dynamically adjust the amount of redundant information stored in memory cells of a wordline on an integrated circuit die based on a bit error rate. For example, in response to a determination that a bit error rate of the wordline is above a threshold, the memory system can store first data items as independent first codewords of an error correction code technique into a first portion of the memory cells of the wordline, generate second data items as redundant information from the first codewords, and store the second data items in a second portion of the memory cells of the wordline. If the bit error rate is below the threshold, third data items can be stored as independent second codewords of the same length as the first codewords in the memory cells of the wordline.
