Abstract: Methods, systems, and devices for rating-based mapping of data to memory are described. A memory system may determine a first rating for a set of data selected for writing to a memory system. The memory system may select a target page of a block in the memory system for writing the set of data based at least in part on a second rating for the target page. The memory system may write the set of data to the target page based at least in part on the first rating for the set of data corresponding to the second rating for the target page.

Abstract: A microwave processing device includes kiln head, which runs through and is connected to the rotary kettle, and multiple parts of kiln head are equipped with microwave feeding inlet, and kiln head is connected with microwave generator via microwave tube; kiln head is connected to feeding mechanism, and rotary kettle is set up with collecting opening and discharging mechanism, and collecting opening is connected with condensing and recycling unit. The microwave processing device makes use of microwave energy to rapidly heat material inside rotary kettle, and rotates rotary kettle at the same time, to make material more uniformly heated and improve material pyrolyzing efficiency, and it can greatly improve pyrolyzing and separating efficiency of material, effectively reduce energy consumption and significantly improve safety of equipment operation; it also avoids secondary pollution to environment caused by burning of heating energy, thus effectively improves economic and social benefits.

Abstract: A rotary furnace using microwave as the energy is provided, and it includes kiln head which runs through and is connected to rotary kettle, multiple parts of the kiln head are equipped with microwave feeding inlet which is used to introduce the external microwave sources into rotary kettle to heat material; kiln head is connected to feeding mechanism, and rotary kettle is set up with collecting opening and discharging mechanism. The Rotary furnace makes use of the microwave energy to rapidly heat material inside rotary kettle, and rotates rotary kettle at the same time, to make material more uniformly heated and improve material pyrolyzing efficiency, and it can greatly improve pyrolyzing and separating efficiency of material, and effectively reduce energy consumption; it also avoids secondary pollution to environment caused by burning of heating energy, thus effectively improves economic and social benefits.

Abstract: A material drying and pyrolyzing method includes the following steps: sending material into rotary kettle; making use of microwave energy to heat material within rotary kettle to pyrolyze and decompose material in order to get decomposed gas and solid substance; condensing and recycling gas generated from the decomposing; recycling and disposing solid substance generated from the pyrolyzing. The method makes use of the microwave energy to rapidly heat material inside rotary kettle, and rotates rotary kettle at the same time to make material more uniformly heated, improve material pyrolyzing efficiency, which can greatly improve pyrolyzing and separating efficiency of material and effectively reduce energy consumption, with the improvement of safety performance of the equipment operation. It also avoids secondary pollution to environment caused by burning of heating energy, thus effectively improves economic and social benefits.
