PROBLEM TO BE SOLVED: To reduce the writing in a nonvolatile memory and to perform versatile atomicity management. SOLUTION: When the process requested to a program executing environment section 202 from a program 201 read out data, the environment section 202 asks a commit buffer managing section 203 to read out data by designating the address and length of the data to be read out. The managing section 203 tries to read out data from a commit buffer 204 first and then from a persistent data storage 205 and returns the read-out value to the environment section 202. The section 202 returns the read-out value to the program 201. |
