The memory error determination device includes a processor configured to: detect a memory element in which an error has occurred in each of a plurality of layers included in a memory being three-dimensionally stacked, specify a position of each memory element in which the error has occurred in each of the plurality of layers, and determine that, when the position of each memory element in which the error has occurred is linearly aligned across a predetermined number of layers among the plurality of layers, the predetermined number being two or more, an error that has occurred in the memory is a soft error due to radiation incident on the memory.

Device for determining soft error occurred in a memory having stacked layers, and computer readable medium storing program thereon for determining the soft error

A machining apparatus is provided with a machine learning device that performs machine learning. The machine learning device performs the machine learning by receiving the input of machining accuracy between a machining shape of a workpiece measured on-machine and design data on the workpiece and machining time of the workpiece measured by a measurement device. Based on a result of the machine learning, the machining apparatus changes machining conditions such that the machining accuracy increases and the machining time becomes as short as possible.

Controller-equipped machining apparatus having machining time measurement function and on-machine measurement function

A control device that performs encoding of data to a code word and decoding from the code word to data by an error correction code is disclosed. The control device has an error correction function by which a correctable error is automatically corrected in the decoding. The control device includes an error correction processing unit which switches error correction codes based on a correction rate, which is outputted from a correction rate calculation unit, of every state so as to perform encoding from data to a code word and decoding from the code word to data and output correction information related to error correction. A lifetime calculation unit calculates a device lifetime which is a current remaining lifetime of a device based on a correction capability value of a current error correction code, a current correction rate, and a failure factor coefficient of a current operation state.

Control device performing lifetime prediction by error correction function

A controller has an error correction capability by including: a state monitoring unit that analyzes a state of a monitoring target and outputs state information; an error correction processing unit that switches error correction codes so that a correction rate for the respective states becomes a value within a predetermined range; and a correction rate calculation unit that calculates the correction rate for the respective states based on the correction result by the error correction processing unit.
