Gain-Cell Embedded DRAM: A Logic-Compatible Alternative for On-Chip Memory
On-chip memory dominates the area and power of nearly every modern chip, yet SRAM, its default solution, is costly: six transistors per bit, leaky, ratioed, and no longer scaling with logic. Conventional embedded DRAM is denser but needs special fabrication that keeps it out of standard processes. This talk makes the case for Gain-Cell embedded DRAM (GC-eDRAM), a fully logic-compatible dynamic memory that is smaller and lower-leakage than SRAM while retaining SRAM-like performance. Its central challenge is limited data retention, which will be surveyed across more than a decade of circuit, technology, and refresh techniques developed to tame it. The talk will then turn to recent directions: silicon-proven macros in advanced process technologies, GC-eDRAM as a substrate for in-memory and associative computing, cryogenic operation, and RAAAM Memory Technologies – the company that is commercializing the technology.
