摘要：
A static random access memory having multiple I/Os includes a memory array (10) of memory cells (42) with columns that are selectively clearable as a function of the associated I/O. The columns are arranged in pairs (34) with each column in the pair (34) associated with the same I/O. A clear signal is input thereto on a line (28) and driven by a driver (30). The clear signal is only associated with the pairs (34) associated with a selected I/O. The remaining columns of memory cells associated with unselected I/Os are not cleared.
