Abstract
A memory system includes a first external device, a second external device, and a multi-port memory device connected to the first and second external devices. The multi-port memory system includes: a first port and a second port connected to the first and second external devices, respectively, a first bank group having at least one memory bank, the first bank group configured to be accessed by the first external device through the first data port; a second bank group having at least one memory bank, the second bank group configured to be accessed by the second external device through the second data port; a third bank group having at least one memory bank, wherein the third bank group is configured to be selectively accessed by the first external device through the first data port or the second external device through the second data port. The multi-port memory system may prevent data collisions which occur when two ports simultaneously attempt to access the same memory bank.
