A Brief History of Test


The history of semiconductor test systems is the subject of this blog post. We’ll turn to printed circuit board testing at another time. Boston-based Teradyne sold its D133 diode tester to Raytheon in 1961. Five years later, it introduced the J259 integrated circuit tester, which had a minicomputer to run the test programs. For many, this marks the beginning of automatic (or automated) tes... » read more

NAND ATE Market Gets Testy


The NAND flash memory market is undergoing big changes. As planar NAND moves further down the 1xnm node regime, suppliers are ramping up devices with new cell structures, interfaces and other features. And on top of that, 3D NAND is beginning to appear in the market. The next-generation NAND devices will enable new applications in the mobile and enterprise markets, but the chips themselves p... » read more
