Abstract: Examples of a method for teaching a transportation position includes correcting the position of an alignment jig having a plurality of sloping surfaces relative to a susceptor pin projecting upwards from an upper surface of a susceptor by lowering a robot hand to bring one of the sloping surfaces into contact with the susceptor pin and causing the susceptor pin to slide on the sloping surfaces by virtue of an own weight of the aliment jig, detecting a position of the alignment jig before and after the positional correction of the alignment jig, and correcting a movement destination information by an amount corresponding to a difference between an initial position and a corrected position of the alignment jig.

Abstract: According to one embodiment, a memory system receives from a host a first write request including a first block identifier designating a first write destination block to which first write data is to be written. The memory system acquires the first write data from a write buffer temporarily holding write data corresponding to each of the write requests, and writes the first write data to a write destination page in the first write destination block. The memory system releases a region in the write buffer, storing data which is made readable from the first write destination block by writing the first write data to the write destination page. The data made readable is a data of a page in the first write destination block preceding the write destination page.

Abstract: According to one embodiment, a memory system manages wear of each of a plurality of blocks in a nonvolatile memory. The memory system receives, from a host, a write request including a parameter specifying a data retention term required for first data to be written.
