  • Patent number: 8456946
    Abstract: A NAND architecture for selecting a word line driver in a DRAM is disclosed. Separately decoded addresses in the low, mid and high ranges are used to select a final word line driver. The output of the word line driver is at a potential negative with respect to ground for a deselected word line and a positive potential more positive than the power supply potential for a selected word line.

  • Patent number: 8406073
    Abstract: A hierarchical DRAM sensing apparatus and method which employs local bit line pairs and global bit lines. A word line selects the cells in a cluster of sense amplifiers, each of the amplifiers being associated with a pair of bit lines. One of the local bit lines is selected for coupling to global bit lines and a global sense amplifier. Clusters are located in a plurality of subarrays forming a bank with the global bit lines extending from each of the banks to the global sense amplifier.

  • Patent number: 8245111
    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.

  • Patent number: 8232588
    Abstract: Methods and apparatuses to increase a surface area of a memory cell capacitor are described. An opening in a second insulating layer deposited over a first insulating layer on a substrate is formed. The substrate has a fin. A first insulating layer is deposited over the substrate adjacent to the fin. The opening in the second insulating layer is formed over the fin. A first conducting layer is deposited over the second insulating layer and the fin. A third insulating layer is deposited on the first conducting layer. A second conducting layer is deposited on the third insulating layer. The second conducting layer fills the opening. The second conducting layer is to provide an interconnect to an upper metal layer. Portions of the second conducting layer, third insulating layer, and the first conducting layer are removed from a top surface of the second insulating layer.

  • Patent number: 8138042
    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.
