Abstract
A memory system including a plurality of ports and a memory core having a plurality of memory banks. Access requests received at the ports are broadcast to the memory banks. Multiple memory banks may be concurrently accessed in response to access requests received on different ports. A memory controller provides the access requests to the memory system, and ensures that a single memory bank is not concurrently accessed by different ports. All access requests are processed with the same latency. If the memory banks include memory cells that must be periodically refreshed, then the memory controller also provides refresh requests to the memory banks. Because multiple memory banks may be concurrently accessed in response to access requests provided on different ports, the memory banks can operate at a lower frequency than the ports.
