摘要: One or more embodiments relate to a static random access memory cell comprising: a first inverter including a first n-channel pull-down transistor coupled between a first node and a ground voltage; a second inverter including a second n-channel pull-down transistor coupled between a second node and the ground voltage; a first n-channel access transistor coupled between a first bit line and the first node of the first inverter, a fin of the first n-channel access transistor having a lower charge carrier mobility than a fin of the first n-channel pull-down transistor; and a second n-channel access transistor coupled between a second bit line and the second node of the second inverter, a fin of the second n-channel access transistor having a lower charge carrier mobility than a fin of the second n-channel pull-down transistor.
