PROBLEM TO BE SOLVED: To provide a device and a method for storing data, with which a FIFO function can be suitably provided for the data of plural systems in small circuit scale. SOLUTION: When data are written in a bank A, for example, in an address control part 240, an address at the time of recording the data of the last bank A outputted from a bank A write address storage part 244 is selected by a selector 246, this address is impressed to a next pointer 247, and the data recording address of this time is stored in the data recording address of the last time as data. Since the link of data streams of plural systems is managed by the next pointer 247, even when the inputted data of any arbitrary system are written in any address, each of systems is distinguished and data can be read in the order of input for each of systems. |
