As seen in Chap. 2, gain-cell (GC) embedded DRAM (eDRAM), or GC-eDRAM in short, is an interesting alternative to static random-access memory (SRAM) and 1-transistor-1-capacitor (1T-1C) eDRAM...
Abstract- A gain cell embedded DRAM (eDRAM) in a 65nm LP process achieves a 1.0 GHz random access frequency by eliminating the write-back operation. The read bitline swing of the 2T1D cell is improved by employing short local bitlines connected to …
替代昂贵的SRAM - 知乎 - 知乎专栏
2024年1月4日 · 3T(三晶体管)和 2T(双晶体管)CMOS eDRAM 增益单元设计是嵌入式动态随机存取存储器电路,与传统 SRAM 相比,每个存储单元使用的晶体管数量更少。 因此密度更高,面积更小。 3T/2T eDRAM 单元使用逻辑器件制造,因此只需进行极少的修改即可在标准 CMOS 工艺中构建。 工业设计表明,使用三个晶体管可实现比 SRAM 高约 2 倍的位元密度。 为此,eDRAM 增益单元(3T 和 2T)可在不改变制造技术的情况下减少片上 SRAM 面积。 如表 I …
