Novel Transistor Gain Cell With Feedback

Close-up of a computer microchip

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

The Solution:

We propose a novel memory macro suitable for deeply scaled CMOS technologies and high-bandwidth applications.
