Embodiments herein provide a data storage device including a non-volatile memory, a second memory, and a controller coupled to the non-volatile memory and the second memory. The second memory is configured to store a plurality of delta queues. Each of the plurality of delta queues includes delta queue entries. The delta queue entries are grouped into one or more logical-to-physical (L2P) pages. Each of the one or more L2P pages is associated with a plurality of logical flash management units (LFMUs) corresponding to a plurality of physical addresses in the non-volatile memory. The controller is configured to determine that a delta queue flush is required. In response to determining that the delta queue flush is required, the controller selects one of the plurality of delta queues to flush, and flushes the one or more L2P pages stored in the one of the plurality of delta queues to the non-volatile memory.

Devices, methods, and computer readable media for control page flush handling

Bit-flip object insertion techniques are provided for use with a non-volatile memory (NVM) wherein an object is inserted into a background image by flipping or inverting one or more bits within the pixels of the background image that correspond to the shape and insertion location of an object being inserted. In an illustrative example, pixels within the background image that correspond to the shape and insertion location of the object are XORed with binary 1s. This flips the bits of those pixels to change the color (hue) and/or intensity (brightness) of the pixels so the object appears in the background image. In other examples, only the most significant bits of pixels in the background image are inverted (flipped). Exemplary latch-based procedures are described herein for high-speed processing on an NVM die. Multiple plane NVM die implementations are also described for massive processing.
