In a memory system, a host controller is coupled to a non-volatile memory (NVM) package (e.g., NAND device). The host controller sends a read command to the NVM package requesting a low latency read operation. Responsive to the read command, a controller in the NVM package retrieves the data and sends the data to an ECC engine for correcting. Following the read command, the host controller sends a read status request command to the controller in the NVM package. Responsive to the read status request, the controller sends a status report to the host controller indicating that some or all of the data is available for transfer to the host controller. Responsive to the report, the host controller transfers the data. An underrun status can be determined to indicate that uncorrected data had been transferred to the host controller.
