摘要:
A multi-headed word line driver circuit incorporates bent-gate transistors to reduce the pitch otherwise achievable for interfacing to tightly-pitched array lines. In certain exemplary embodiments, a three-dimensional memory array includes multiple memory blocks and array lines traversing horizontally across at least one memory block. Vertical active area stripes are disposed beneath a first memory block, and a respective plurality of bent-gate electrodes intersects each respective active area stripe to define individual source/drain regions. Every other source/drain region is coupled to a bias node for the active area stripe, and remaining source/drain regions are respectively coupled to a respective array line associated with the first memory block, thereby forming a respective first driver transistor for the respective array line.
摘要(中):
多头字线驱动电路包括弯栅晶体管,以减少为了与紧密排列的阵列线连接而实现的间距。 在某些示例性实施例中,三维存储器阵列包括穿过至少一个存储器块水平横越的多个存储器块和阵列线。 垂直有源区条纹设置在第一存储块下方,并且相应的多个弯曲栅电极与每个相应的有源区条纹相交以限定各个源/漏区。 每个其它源极/漏极区域耦合到用于有源区域条纹的偏置节点,并且剩余的源极/漏极区域分别耦合到与第一存储器模块相关联的相应阵列线,从而形成用于相应阵列的相应的第一驱动器晶体管 线。
