Abstract
Java Card technology provides interoperability, platform independence and high level security, java language has inherited problems that are slow execution speed and data loss particularly when power is gone while recording.So Java Card System first backups the previous data aboutJava objects into the transaction mechanism, then writes new data into Flash, during the downloading and execution of Java Cards application called an applet.It is caused by too many Flash writing operations.It makes Java Card much slower.In this paper, we have proposed a method to reduce the number of writing that new transactionmechanism in RAM. With our approach, the number of Flash writing and the downloading speed are reduced by 30% and 50% separately.
