Abstract
A method of operating a memory macro includes receiving a first signal indicating a first operational mode of the memory macro, receiving a second signal indicating a second operational mode of the memory macro, generating, by a first logic circuit, a third signal and a fourth signal based on the first signal and a fifth signal thereby causing a change in the first operational mode of the memory macro, and generating, by a second logic circuit, the fifth signal and a sixth signal based on at least the second signal and thereby causing a change in the second operational mode of the memory macro. The first logic circuit is coupled to a first memory cell array and a first IO circuit. The second logic circuit is coupled to a first and second set of word line driver circuits.
