Patent ID: 7324368

Claim:
An integrated circuit memory comprising: at least one memory cell having a first state and a second state corresponding to storage of different values of a data bit; and a power supply control circuit operable to supply power to said at least one memory cell and having a supply input coupled to a power source and a supply output coupled to said at least one memory cell; wherein said power supply control circuit includes at least a first gate and a second gate and is responsive to a write assist signal to switch at least one of said first gate and said second gate such that: when not writing to said at least one memory cell said power supply control circuit provides a low resistance path between said supply input and said supply output; and when writing to said at least one memory cell said power supply control circuit provides a high resistance path, with a resistance greater than said low resistance path, between said supply input and said supply output so that said at least one memory cell is more readily switched between said first state and said second state.
