Abstract:
A multi-ported memory that supports multiple read and write accesses is described herein. The multi-ported memory may include a number of read/write ports that is greater than the number of read/write ports of each memory bank of the multi-ported memory. The multi-ported memory allows for at least one read operation and at least one write operation to be received during the same clock cycle. In the event that an incoming write operation is blocked by the at least one read operation, data for that incoming write operation may be stored in a cache included in the multi-port memory. That cache is accessible to both write operations and read operations. In the event than the incoming write operation is not blocked by the at least one read operation, data for that incoming write operation is stored in the memory bank targeted by that incoming write operation.
