    Abstract: In connection with rise and fall of a word line bias, the present invention adopts a procedure such that a diffusion region voltage Vs on a memory transistor side is changed, and after the voltage Vs passes a certain intermediate value Vsx, a gate voltage Vmg of the memory transistor is changed. Alternatively, there is adopted a procedure such that the gate voltage Vmg of the memory transistor is changed, and after the voltage Vmg passes a certain intermediate value Vmgx, the diffusion layer voltage Vs on the memory transistor side is changed. The values of Vsx and Vmgx are determined from the magnitude of the electric field in a gate insulating film not causing FN tunneling electron injection that causes a change in threshold voltage and the magnitude of a potential barrier against holes not causing BTBT hot hole injection.

    Abstract: A semiconductor integrated circuit (LSI) in which control information for determining a voltage or a width of a pulse produced itself can easily be set in parallel with other LSIs, and set information can be corrected easily. From an external evaluation device, a voltage of an expected value is supplied in overlapping manner to a plurality of LSIs each having a CPU and a flash memory. Each LSI incorporates a comparison circuit comparing an expected voltage value and a boosted voltage generated in itself. The CPU refers to a comparison result and optimizes control data in a data register for changing a boosted voltage. The CPU controls the comparison circuit and the data register and performs trimming in a self-completion manner, thereby making, trimming on a plurality of LSIs easily in a parallel manner and a total test time reduced.

    Abstract: The read speed of an on-chip nonvolatile memory enabling electric rewrite is increased. The nonvolatile memory has a hierarchal bit line structure having first bit lines specific to each of a plurality of memory arrays, a second bit line shared between the plurality of memory arrays, a first selector circuit selecting the first bit line for each of the memory arrays to connect the selected first bit line to the second bit line, and a sense amp arranged between the output of the first selector circuit and the second bit line. The hierarchal bit line structure having the divided memory arrays can reduce the input load capacity of the sense amp.

    Abstract: A method and apparatus for the anaerobic methane fermentation treatment of a wastewater containing a sulfur compound. An oxidizing agent is added to an organic wastewater to oxidize the sulfur compound contained therein to molecular sulfur before the anaerobic treatment step. The wastewater is then introduced into the anaerobic treatment step for the methane fermentation treatment thereof. The amount of the oxidizing agent to be added to the wastewater is controlled using as an indicator the concentration of the residual oxidizing agent in the water flowing into the anaerobic treatment step and/or the concentration of hydrogen sulfide in a biogas generated. The oxidizing agent may be ozone, hydrogen peroxide, sodium hypochlorite or a bromine based oxidizing agent. When the concentration of hydrogen sulfide in a biogas generated in the anaerobic treatment step is used as said indicator, the oxidizing agent may be suitably added such that the concentration of hydrogen sulfide is 3% or less.
