A programmable logic array integrated circuit has a number of programmable logic modules which are grouped together in a plurality of logic array blocks. The mixture is humidified and shaped and then heated to a formation temperature sufficient to melt the raw material to develop an oxygen-containing molten liquid phase. The preferred laser is a Ti:Sapphire amplified, frequency-doubled Erbium-doped fiber laser system, providing light pulses of approximately 100 femtosecond duration, each with an energy of between about 1 nanojoule and 1 millijoule, and preferably at a pulse repetition rate of between 500 Hz and 1 GHz. The method also includes mapping the summation weight value of a selected instruction that is attempting to access system memory to a memory access control, each memory access control specifying a manner of handling data fetching operations. The clock adjusting unit adjusts the clock divisor according to the output pixel clock signal, the output vertical reference signal, and an input vertical reference signal having an input frame rate. Low voltage buffer driving level converters are both replaced by a single said level converter.
