Abstract:
1. A plug-in card storage device comprising: a plug-in card including a memory to store received input data and an error correction circuit to be equipped electrically connectable to the memory and to correct an error in input data outputted from the memory; a device body to have the plug-in card implemented therein; and a processor to determine whether or not to activate the error correction circuit, by calculating a reliability index value of the plug-in card based on an error rate of the memory provided in the plug-in card implemented in the device main body, so as to approximate the reliability index value to a reference value; wherein the reliability index value is at least one of a card error rate and an average failure time of the plug-in card storage device, the card error rate is obtained by adding a hard failure rate of the plug-in card and a hard failure rate of the device body and a soft error rate of the memory, and the average failure time is an inverse of the card error rate.
