The present disclosure includes systems and techniques relating to FIFO queue memory. In general, in one implementation, a queue memory receives and stores information and supports first-in-first-out read and out-of-order read operations with information shifting within the memory relative to a read operation. The queue memory can include a write pointer that increments upon a write operation and decrements upon the read operation, a read pointer that identifies an oldest read entry of the queue memory when the read operation is a first-in-first-out read and that identifies a selected entry of the queue memory when the read operation is an out-of-order read, and a multiplexer operative to select entries of the queue memory responsive to the read pointer.
