Abstract: The present invention provides a method for depth removal of a volatile organic compound (VOC) in polymer resins and products thereof by means of a steam distillation method and apparatus thereof and significantly reducing the odor of the polymer resins and products thereof. The method provided in the present invention can further remove residual inorganic ash in the polymer resins. In the method, saturated steam at a certain temperature continuously keeps in contact with materials for a certain period of time, the VOC and an inorganic small molecule (ash) adsorbed on the surface of a polymer and wrapped inside the polymer are promoted to be enriched in a gas phase or a liquid phase and discharged, so as to reduce the VOC and ash in polymer materials, and the odor of the polymer resins or materials is decreased to a better level.

Abstract: In an aspect, a method for managing a logic to physical (L2P) mapping table of a memory device is disclosed. A first configuration corresponding to a file is received from a host device with the memory device. Transmitting an L2P dirty entry notification associated with the file to the host device is refrained from. The L2P dirty entry notification indicates that an L2P entry of an L2P mapping table stored in the host device has become dirty. In response to the refraining, a first confirmation is transmitted to the host device.

Abstract: Disclosed herein are system, method, and computer program product aspects for managing a storage system. In an aspect, a host device may generate a configuration corresponding to a file and transmit the configuration to a memory device, such as 3D NAND memory. The configuration instructs the memory device to refrain from transmitting a logic-to-physical (L2P) dirty entry notification to the host device. The L2P dirty entry notification corresponds to the file. The host device may also generate a second configuration corresponding to the file and transmit the second configuration to the memory device. The second configuration instructs the memory device to resume transmitting the L2P dirty entry notification corresponding to the file to the host device.
