Abstract
A memory cell includes a first active region providing a plurality of first nano-structures for a write-port pass-gate transistor, a second active region providing a plurality of second nano-structures for a write-port pull-up transistor, and a third active region providing a plurality of third nano-structures for a read-port pull-down transistor. The first active region has a first width, the second active region has a second width, and the third active region having a third width. The third width is larger than the first width, and the first width is larger than the second width.
