As microprocessors enter the highly multi-core/multi-threaded era, higher density, lower latency embedded memory will be required to meet cache design needs. This paper describes a 500MHz random cycle Silicon on Insulator (SOI) embedded DRAM macro which features a three-transistor micro sense amplifier, realizing significant performance gains over traditional array design methods. To address the realities of process integration, we describe the features and issues associated with integrating this DRAM into SOI technology, including deep trench processing and floating body effects. After a brief description of the macro architecture, details are provided on the three-transistor micro sense amplifier scheme, which is key to achieving a high transfer ratio with minimal area overhead. The paper concludes with hardware results and a summary. © 2008, IEEE. All rights reserved.
