Abstract
A memory circuit includes a bit cell that receives a word line, complementary bit lines and an array supply voltage; a word line driver coupled to the word line, the word line driver receiving one of the array supply voltage and a periphery supply voltage; and a word line suppression circuit coupled to the word line. The word line suppression circuit includes a diode and a switch coupled in series. The switch is responsive to the array supply voltage. The word line suppression circuit limits a word line voltage to a value lower than the array supply voltage such that the static noise margin (SNM) of the bit cell is increased.
