Abstract: The present invention relates to an apparatus and method for indicating flash memory life. While data is being stored in a flash memory, the number of writes in a plurality of blocks of the flash memory increases. The amount of flash memory life is calculated on the basis of the number of write times in the plurality of blocks. The calculated amount of life can be transmitted to a host. In addition, when the calculated amount of life is greater than a threshold value, a signal providing notice that the life of the flash memory has reached a dangerous level can be output.

Abstract: A CFRP plate having a steel plate wherein a weld nut is welded is integrally stacked, and a manufacturing method are provided. The CFRP plate is formed by interposing a steel plate having a weld nut welded to a lower surface between two adjacent CFRP layers. A foam is interposed between a layer when the steel plate is disposed and a layer below the layer when the steel plate is disposed. The guide pins are fitted into the steel plate, a second layer, and the foam, forming an aperture in a portion of a second layer where the weld nut is positioned. A grove is formed accommodating the weld nut in the foam positioned below the aperture. A resin is injected when a temporary bolt is fitted into the weld nut, and the temporary bolt is removed after the resin is injected.
