As one of the few vendors of the legacy DRAM which has a supply problem, LAPIS Semiconductor provides a diverse lineup of PKG products and KGD chips most suitable for SiP, on a long-term stable basis. Also, we offer a quick support which only a domestic (Japan) manufacturer is capable of.




Legacy DRAM

While larger and faster DRAM occupies a larger market share, LAPIS Semiconductor provides smaller DRAM, which is difficult to obtain in these days, on a long-term stable basis. LAPIS Semiconductor provides not only standard products, which feature a wider range of operating temperature and a smaller package, but also customized products in accordance with requirements by customers.




Synchronous DRAM for SiP

LAPIS Semiconductor provides chips (KGD) as a wafer in the quality the same as the PKG product, so that DRAM for SiP can achieve space- and cost-saving.
