The transaction command processing logic is used to process the commands in the command queue. The logic organizes the commands to the memories in such a way that data throughput is maximized. Bank opening and closing cycles are used for data transfers. The logic reviews the entire command queue for look-ahead of which banks have to be accessed in the future and ensures that the programed memory timing conditions are met. This flexibility allows the controller to be tuned to extract the maximum performance out of memories. During processing, the controller examines the commands and issues the appropriate set of signals to the memory.
