MEMORY STRUCTURE WITH SELF-ADJUSTING CAPACITIVE COUPLING-BASED READ AND WRITE ASSIST
Disclosed is a memory structure that includes wordlines (WL) and cell supply lines (CSL) positioned between and parallel to voltage boost lines (VBLs). The VBLs enable capacitive coupling-based voltage boosting of the adjacent WL and/or CSL depending on whether a read or write assist is required.

During a write operation, one VBL adjacent to the WL for a selected row can be charged to create a coupling capacitance with the WL only and thereby boost the Vwl for a write assist. The coupling capacitances created by charging VBLs in the structure is self-adjusting in that as the length of the rows increase so do the potential coupling capacitances.
