Abstract
A memory circuit includes first and second memory segments coupled to first and second write lines, and first and second write line circuits coupled to the first and second write lines and configured to receive first and second data signals. The first and second data signals have complementary low and high logical states during a write operation to the first or second memory segment, and each of the first and second data signals has the low logical state during a masked write operation to the first or second memory segment. The first and second write line circuits output, to the first and second write lines, first and second write line signals responsive to the first and second data signals during the write operation and float the first and second data lines during the masked write operation.
