MEMORY SYSTEM FOR CONTROLLING READING FROM NON-VOLATILE MEMORY

摘要

According to one embodiment, a system includes first to third managers and a storage unit. The first manager generates read requests corresponding to read-unit data items read by a read command received from an device, and manages first information indicating the state of transmission of the read-unit data items to the device. The storage unit temporarily stores the read-unit data items read from nonvolatile memories in a random order, based on the read requests. The second manager manages second information indicating whether each read-unit data item has been read from the nonvolatile memories. The third manager transmits, based on the first and second information, the read-unit data items to the device in an order designated by the read command, the read-unit data items being stored in the storage unit in a random order.

主权项

1. A memory system comprising:
nonvolatile memories; a first manager configured to generate, by a read command received from an external device, a plurality of read requests corresponding to a plurality of read-unit data items read by the read command, and to manage first information indicating a state of transmission of the read-unit data items to the external device; a storage unit configured to temporarily store the read-unit data items read from the nonvolatile memories in a random order, based on the read requests; a second manager configured to manage second information indicating whether each of the read-unit data items has been read from the nonvolatile memories; and a third manager configured to transmit, based on the first information and the second information, the read-unit data items to the external device in an order designated by the read command, the read-unit data items being stored in the storage unit in a random order.
