Memory and Logic devices constitute the greatest volume of semiconductor devices in the industry. Every year devices require more and more memory and VEM works with producers to keep up with the demand. Memory devices include DRAM, SRAM, and non-volatile memory devices or flash memory devices. Logic devices include microprocessors, micro-controllers, ASIC's, and PLD's. For decades, leading logic and memory companies have been innovating with new materials to get to the next generation of devices. VEM has been working with many of the largest device suppliers throughout that time.
