  • Patent number: 7981756
    Abstract: A process of forming a semiconductive capacitor device for a memory circuit includes forming a first capacitor cell recess and a second capacitor cell recess that are spaced apart by a capacitor cell boundary of a first height. The process includes lowering the first height of the capacitor cell boundary to a second height. A common plate capacitor bridges between the first recess and the second recess over the boundary above the second height and below the first height.

  • Publication number: 20110161783
    Abstract: An apparatus and method is described herein directly matching coded tags. An incoming tag address is encoded with error correction codes (ECCs) to obtain a coded, incoming tag. The coded, incoming tag is directly compared to a stored, coded tag; this comparison result, in one example, yields an m-bit difference between the coded, incoming tag and the stored, coded tag. ECC, in one described embodiment, is able to correct k-bits and detect k+1 bits. As a result, if the m-bit difference is within 2k+2 bits, then valid codes—coded tags—are detected. As an example, if the m-bit difference is less than a hit threshold, such as k-bits, then a hit is determined, while if the m-bit difference is greater than a miss threshold, such as k+1 bits, then a miss is determined.

  • Publication number: 20110079837
    Abstract: A capacitor includes a substrate (110, 210), a first electrically insulating layer (120, 220) over the substrate, and a fin (130, 231) including a semiconducting material (135) over the first electrically insulating layer. A first electrically conducting layer (140, 810) is located over the first electrically insulating layer and adjacent to the fin. A second electrically insulating layer (150, 910) is located adjacent to the first electrically conducting layer, and a second electrically conducting layer (160, 1010) is located adjacent to the second electrically insulating layer. The first and second electrically conducting layers together with the second electrically insulating layer form a metal-insulator-metal stack that greatly increases the capacitance area of the capacitor. In one embodiment the capacitor is formed using what may be referred to as a removable metal gate (RMG) approach.

  • Publication number: 20100146368
    Abstract: A processor may comprise a cache, which may be divided into a first and second section while the processor operates in a low-power mode. A cache line of the first section may be fragmented into segments. A first encoder may generate first data bits and check bits while encoding a first portion of a data stream and a second encoder may, separately, generate second data bits and check bits while encoding a second portion of the data stream. The first data bits may be stored in a first segment of the first section and the check bits in a first portion of the second section that is associated with the first segment. The first decoder may correct errors in multiple bit positions within the first data bits using the check bits stored in the first portion and the second decoder may, separately, decode the second data bits using the second set of check bits.
