SRAM having wordline up-level voltage adjustable to assist bitcell stability and design structure for same
Abstract:
An integrated circuit that includes memory containing wordlines and bitcells having SRAM storage elements and being connected to the wordlines. Wordline up-level assist circuitry is provided that is designed and configured to provide a plurality of selectable voltage values that can be selected to provide the wordline up-level voltage that is provided to the bitcells during a memory read cycle and/or write cycle. In one example, the voltage value selected is selected based on characterization of the as-fabricated bitcells so as to decrease the likelihood of the bitcells experiencing a stability failure.
