The Problem

Embedded memories, typically implemented with a 6T SRAM bitcell consume an ever growing share of the total silicon area and power. Gain cell embedded DRAM (GC-eDRAM) is an alternative to 6T SRAM, offering higher density, lower leakage, and 2-port operation. However, gain cells:

• Rely on dynamic storage
• Results in very low data retention times
• Increases the power consumption
• Reduces memory availability
