A design structure comprising a static random access memory (SRAM) (200, 400) comprising a plurality of SRAM cells (204), a plurality of wordlines (WLO-WLN) and a voltage regulator (240, 240′, 300, 516) for driving the wordlines with a wordline voltage signal (VWLP). The wordline voltage signal is determined so as to reduce the likelihood of occurrence of read-disturbances and other memory instabilities. In one embodiment, the wordline voltage signal is determined as a function of the metastability voltage (VMETA) of the SRAM cells and an adjusted most positive down level voltage (VAMPDL) that is a function of a predetermined voltage margin (VM) and a most positive down level voltage (VMPDL) that corresponds to the read-disturb voltage of the SRAM cells.
A design structure instantiated in a machine readable medium for designing, manufacturing, or testing an integrated circuit, the design structure comprising:
