  • Publication number: 20250063743
    Abstract: Some implementations described herein provide techniques and apparatuses for an integrated circuit device including a trench capacitor structure that has a merged region. A material filling the merged region is different than a material that is included in electrode layers of the trench capacitor structure. Furthermore, the material filling the merged region includes a coefficient of thermal expansion and a modulus of elasticity that, in combination with the architecture of the trench capacitor structure, reduce thermally induced stresses and/or strains within the integrated circuit device relative to another integrated circuit device having a trench capacitor structure including a merged region and electrode layers of a same material.

  • Patent number: 6888754
    Abstract: This invention provides a memory array and its peripheral circuit with byte-erase capability. The advantage of this invention is the ability to access bytes for program, erase, and read operations. This invention allows this access with the addition of one word line switch and one source line switch for each byte to be accessed for program, erase, and read operations. Also, this invention utilizes a new bias condition to lessen the voltage stress on the high voltage device. In addition, this invention utilizes separate and dedicated power supplies for the local word line driver circuits and for the local source line driver circuits. This is coupled with the partitioning of the main memory array into sub-arrays of 8 columns. This allows the placing of high voltage only on the selected 8 column (byte) subarray. This also substantially lessens the voltage stress on the memory cells and enhances long-term reliability.
