Abstract: Provided are a system and method for managing a neuromorphic memory. The system includes a memory having a multi-dimensional lattice structure, a prescience estimator (PSE) configured to separately estimate memory use of two or more data sets and determine a sequence of inputting the two or more data sets to the memory, and a prescience manager (PSM) configured to allocate memory regions in which the two or more data sets will be stored according to estimation results of the PSE, store the data sets, and perform learning and inference.

Abstract: This application relates to a mechanical button apparatus that includes a body where an upper portion thereof is closed and a lower portion thereof is opened and a bottom plate attached on a display screen of a display apparatus to cover the opened lower portion. The body includes an aperture member including a wing set expanded or contracted in a rotation direction of the body. The body also includes a photovoltaic (PV) cell array substrate including a PV cell configured to generate power for charging a battery and an optical sensor configured to convert light signals, reflected by the expanded or contracted wing set, into electrical signals. The body further includes a circuit substrate configured to operate with the power charged into the battery, calculate number of rotation manipulations of the body by using the electrical signals, and transmit the calculated number of rotation manipulations to the display apparatus.
