TRANSCATION PROCESSING METHOD USING A RAM TRANSACTION BUFFER

摘要

A transaction processing method using an RAM(Random Access Memory) transaction buffer is provided to shorten a processing time by reducing the frequency of EEPROM(Electrically Erasable and Programmable Read Only Memory) writing for processing transaction, thereby improving the performance of a smart card. A transaction processing method using an RAM(Random Access Memory) transaction buffer comprises the following steps of: starting a transaction process according to a transaction start signal(ST-2); storing data inputted or requested by a transaction processing routine in the RAM transaction buffer(ST-4); determining whether there is commit transaction and performing internal transaction if the commit transaction is generated(ST-6); and performing automatic roll back of the transaction if the commit transaction is not generated(ST-7).
