Abstract: A mapping information management method, a memory storage device, and a memory control circuit unit are provided. The method includes: receiving a write command instructing storing of first data from a host system; storing the first data to a rewritable non-volatile memory module according to the write command; updating mapping information corresponding to the storing of the first data; storing the mapping information to the rewritable non-volatile memory module; generating assistant information according to first part information of the mapping information, where the assistant information is not stored into the rewritable non-volatile memory module; and transmitting second part information of the mapping information and the assistant information to the host system to provide information related to the storing of the first data.

Abstract: A climbing training machine has a fixed frame, a movable frame fitted to the fixed frame, a telescopic screw bar connected to the fixed frame and the movable frame, an elevating frame pivoted on the movable frame at a side distal to the fixed frame, a supporting frame having opposite ends pivoted on a middle section of the elevating frame and the fixed frame and a running belt mounted on the elevating frame for rotation. The elevating frame can adjust its slope for the user to walk or run on the belt in various difficult levels.
