ABSTRACT:
A static random access memory (SRAM) comprising a plurality of SRAM cells, a plurality of wordlines (WL0-WLN) and a voltage regulator 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.
