Together, Lattice and Silicon Image employed 1,455 at the end of last year. Lattice did not say how many lost their jobs in last spring's layoff but if it reduced the work force by 100 then a 13 percent cut would eliminate about 175 jobs. Lattice is the smallest of three big companies in the programmable chip market. Intel is in the process of buying one of Lattice's larger competitors, Altera, in a $16.7 billion deal, and Wall Street analysts have long considered the Portland company an acquisition target amid ongoing consolidation in the chip industry.
