Abstract:
One illustrative device disclosed herein includes a first pull-up transistor positioned in a first P-type nano-sheet and a first pull-down transistor and a first pass gate transistor positioned in a first N-type nano-sheet. The device further includes a second pull-up transistor positioned in a second P-type nano-sheet and a second pull-down transistor and a second pass gate transistor positioned in a second N-type nano-sheet. The device further includes a read pull-down transistor and a read pass gate transistor positioned in a third N-type nano-sheet. The device also includes a first shared gate structure positioned adjacent the first pull-up transistor and the first pull-down transistor and a second shared gate structure positioned adjacent the second pull-up transistor, the second pull-down transistor and the read pull-down transistor.
