Abstract
When a memory system supports different read modes with different read latencies, such as reference read and self-referenced read, read data conflicts can occur for data returned from the memory cells in response to the issued read commands. To support such mixed read modes, embodiments for the memory controller can include separate queues for fast read commands and slow read commands and coordinate the issuing of the two command types. A mixed read coordinator can track issued slow read commands and determine whether a fast read command can be issued. The issued commands are ordered such that they are correctly associated with the read data returned from the memory cells.
