Abstract
A data storage device includes a memory device and a controller coupled to the memory device. When data received by the controller, from a host device or from a non-volatile memory of the data storage device, the controller maintains table tracking the location of the data. The table may include a current location of the data in a volatile memory of the controller or the data storage device as well as the current location of the data a latch of the non-volatile memory. The table may further associate the location with a logical block address, such that when the host device requests the data not yet programmed to the non-volatile memory or data that is part of a data relocation operation, the controller may utilize the table to locate the relevant data and provide the data to the host device.
