Abstract:
A memory device with a logical-to-physical (LTP) bank mapping cache that supports multiple read and write accesses is described herein. The memory device allows for at least one read operation and one write operation to be received during the same clock cycle. In the event that the incoming write operation is not blocked by the at least one read operation, data for that incoming write operation may be stored in the physical memory bank corresponding to a logical memory bank that is associated with the incoming write operation. In the event that the incoming write operation is blocked by the at least one read operation, then data for that incoming write operation may be stored in an unmapped physical bank that is not associated with any logical memory bank.
