Abstract
A dual port memory includes a mechanism for preventing collisions. The memory includes dual port bit cells arranged in rows and columns and each bit cell stores a data bit. The memory also includes a wordline unit that may provide a respective write wordline signal and a respective read wordline signal to each row of bit cells. The wordline unit may also selectively inhibit the read wordline signal for a given row based upon address information that is indicative of whether a write operation will be performed to the given row.
