MG63P/64P/65P
0.25µm Embedded DRAM/Customer Structured Arrays
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 experi-
ence 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 pro-
duction-proven 64- Mbit DRAM manufacturing process.
The 0.25 µm family provides significant performance, density, and power improvement over previous
0.30 µm and 0.35 µm technologies. An innovative 4-transistor cell structure provides 30 to 50% less
power and 30 to 50% more usable gates than traditional cell designs. The Oki 0.25 µm family operates
using 2.5-V VDD core with optimized 3-V I/O buffers. The 3-, 4-, and 5-layer metal MG63P/64P/65P
CSA series contains 21 devices each, offering up to 868 I/O pads and over 5.4M raw gates. These CSA
array sizes are designed to fit the most popular quad flat pack (QFP), low profile QFPs (LQFPs), thin
QFPs (TQFPs), and plastic ball grid array (PBGA) packages. Oki uses the Artisan Components memory
compiler which provides high performance, embedded synchronous single- and dual-port SRAM mac-
rocells for CSA designs. As such, the MG63P/64P/65P series is suited to memory-intensive ASICs and
high volume designs where fine tuning of package size produces significant cost or real-estate savings.
The embedded SDRAM represents part of Oki’s menu of major IP core functions for the 0.25 µm ASIC
products. Other functions include ARM7TDMI, Gb Ethernet MAC, PLL, PCI and others in planning.
