    • A memory cell system/method incorporating reduced transistor counts and/or improved design-for-manufacturability (DFM) is disclosed. The system/method incorporates cross-coupled feedthru (3410) / feedback (3420) amplifiers to implement memory cell state memory, wherein the feedback amplifier incorporates a multi-state output drive capability (3423) allowing the memory cell to be read/written using only one access device (3430) connected to the output (3412) of the feedthru (3410) amplifier. The multi-state output drive capability (3423) modulates the feedback amplifier (3420) drive strength to enable reading/writing of the feedthru amplifier (3410) state with greatly reduced memory cell input fan-in requirements. The invention anticipates replacement of traditional DP/8T/6T/4T memory cell structures with corresponding 6T/6T/5T/3T memory cell configurations, resulting in a 16% - 25% transistor reduction depending on memory array application context.
    • 公开了结合减少的晶体管计数和/或改进的可制造性设计(DFM)的存储器单元系统/方法。 该系统/方法包含交叉耦合馈通(3410)/反馈(3420)放大器以实现存储器单元状态存储器,其中反馈放大器包含允许使用多状态输出驱动能力(3423) 只有一个接入装置(3430)连接到馈通(3410)放大器的输出(3412)。 多状态输出驱动能力(3423)调制反馈放大器(3420)的驱动强度,以使得能够读取/写入馈通放大器(3410)状态,同时大大降低存储器单元输入扇入要求。 本发明预期用相应的6T / 6T / 5T / 3T存储器单元配置取代传统的DP / 8T / 6T / 4T存储器单元结构,根据存储器阵列应用上下文,导致晶体管减少16%-25%。
