DUAL PORT MEMORY DEVICE HAVING DUAL MEMORY INTERFACE, MEMORY DEVICE AND METHOD OF OPERATING THE DUAL PORT MEMORY DEVICE

摘要

A dual port memory device having dual memory interface, a memory device and a method of operating the dual port memory device are provided to connect processors with different memory interfaces selectively. A dual port memory device(100) includes a memory array(160), a dual interface part(180) and a first memory interface part. The dual interface part accesses the memory array according to first type memory interface or accesses the memory array according to second type memory interface on the basis of a control signal and an address inputted through a first port in response to a selection signal. The first memory interface part accesses the memory array through the second type memory interface on the basis of a control signal and an address inputted through a second port.
