A method includes, in at least one aspect, receiving a command for a group of data units to be transmitted to a host in a first sequence; for each data unit of the group of data units, receiving an identifier of the data unit and a signal indicating that the data unit has been retrieved and processed for errors, wherein the identifiers and the signals are received in accordance with the group of data units being retrieved from one or more memory devices in a second sequence that is different from the first sequence; tracking the group of data units retrieved in the second sequence; determining, by processing circuitry, that the group of data units has been retrieved and processed for errors; and initiating transmission of the group of data units to the host in accordance with the first sequence.

Controller for reading data from non-volatile memory

The present disclosure includes systems and techniques relating to solid state drive controllers. In some implementations, a device includes a buffer that holds a block of data corresponding to a command from a host. The command identifies the block of data and a logical sequence in which the identified block of data is to be transmitted. In response to the command, a data retriever included in the device retrieves the portions of the block of data from non-volatile memory units in a retrieval sequence that is different from the logical sequence. When the device receives multiple commands identifying multiple blocks of data, the device services the commands in parallel by retrieving portions of blocks of data identified by both commands.
