Legacy DRAM Overview

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.
