DESCRIPTION
Oki’s 0.25 µm MG63P/64P/65P Application-Specific Integrated Circuit (ASIC) provides the ability to embed large blocks of Synchronous DRAM (SDRAM) into an embedded array architecture called the Customer Structured Array (CSA). Utilizing Oki’s leadership in DRAM technologies and wide experience of embedding SDRAM in logic products, Oki is able to integrate SDRAM and ASIC technology. The merged DRAM/ASIC process efficiently implements the Oki stacked capacitor memory cell. The MG63P/64P/65P CSA series uses three, four, and five metal process layers, respectively, on 0.25 µm drawn (0.18 µm L-effective) CMOS technology. The semiconductor process is adapted from Oki’s production-proven 64- Mbit DRAM manufacturing process.

FEATURES
• 0.25µm drawn 3-, 4-, and 5-layer metal CMOS
