  • Patent number: 9361995
    Abstract: A non-volatile memory device comprises a semiconductor substrate of a first conductivity type. An array of non-volatile memory cells is located in the semiconductor substrate and arranged in a plurality of rows and columns. Each memory cell comprises a first region on a surface of the semiconductor substrate of a second conductivity type, and a second region on the surface of the semiconductor substrate of the second conductivity type. A channel region is between the first region and the second region. A word line overlies a first portion of the channel region and is insulated therefrom, and adjacent to the first region and having little or no overlap with the first region. A floating gate overlies a second portion of the channel region, is adjacent to the first portion, and is insulated therefrom and is adjacent to the second region. A coupling gate overlies the floating gate. A bit line is connected to the first region.

  • Publication number: 20160150742
    Abstract: A flue gas treatment apparatus has a flue gas inlet, a treated gas outlet downstream of the flue gas inlet, and a gas flow path therebetween. The flue gas treatment apparatus comprises a particulate removal device. A first heater is downstream of the particulate removal device. The first heater heats the flue gas to a first treatment temperature. A first catalytic converter is downstream of the first heater for eliminating at least some CO and SO2 from the flue gas. A second heater is downstream of the first catalytic converter for heating the flue gas to a second treatment temperature. A second catalytic converter is downstream of the second heater for eliminating at least some NOx from the flue gas. At least a first fan forces the flue gas from the flue gas inlet to the treated gas outlet.

  • Publication number: 20160133639
    Abstract: A memory device with memory cell pairs each having a single continuous channel region, first and second floating gates over first and second portions of the channel region, an erase gate over a third portion of the channel region between the first and second channel region portions, and first and second control gates over the first and second floating gates. For each of the pairs of memory cells, the first region is electrically connected to the second region of an adjacent pair of memory cells in the same active region, and the second region is electrically connected to the first region of an adjacent pair of the memory cells in the same active region.

  • Publication number: 20160117174
    Abstract: A processing method supporting out-of-order execution (OOE) includes load-hit-store (LHS) hazard prediction at the instruction execution phase, reducing load instruction rejections and queue flushes at the dispatch phase. The instruction dispatch unit (IDU) detects likely LHS hazards by generating entries for pending stores in a LHS detection table. The entries in the table contain an address field (generally the immediate field) of the store instruction and the register number of the store. The ISU compares the address field and register number for each load with entries in the table to determine if a likely LHS hazard exists and if an LHS hazard is detected, the load is dispatched to the issue queue of the load-store unit (LSU) with a tag corresponding to the matching store instruction, causing the LSU to dispatch the load only after the corresponding store has been dispatched for execution.

  • Patent number: 9123401
    Abstract: A non-volatile memory device that includes N planes of non-volatile memory cells (where N is an integer greater than 1). Each plane of non-volatile memory cells includes a plurality of memory cells configured in rows and columns. Each of the N planes includes gate lines that extend across the rows of the memory cells therein but do not extend to others of the N planes of non-volatile memory cells. A controller is configured to divide each of a plurality of words of data into N fractional-words, and program each of the N fractional-words of each word of data into a different one of the N planes of non-volatile memory cells. The controller uses a programming current and a program time period for the programming, and can be configured to vary the programming current by a factor and inversely vary the program time period by the factor.
