ABSTRACT:
A memory device having a dual port function includes a memory cell array and a switching unit. The memory cell array has a first port and a second port. The switching unit assigns first data received through a data bus to the first port in response to a leading edge of a clock signal and assigns second data received through the data bus to the second port in response to a trailing edge of the clock. Methods of operating memory devices having a dual port mode are also disclosed.
