| Abstract(in English) | Non-volatile memory (NVM) using magnetic tunnel junction (MTJ) devices can prevent the increase in leakage current, which has become a problem in recent years, because it allows fine-grained power supply interruption. However, MTJ has a problem of large store energy. In this study, we propose an NVSRAM that achieves low energy consumption by applying Approximate Storing, which divides the data bit strings and reduces the store time in the parts that do not require accurate store. The energy reduction during image storage was evaluated by simulation in the 65nm process. |
