A system including a communication interface, a memory, and a processor. The communication interface is configured to receive data. The memory is divided into a first retention region and a second retention region, wherein the first retention region is configured to store data for a first predetermined period of time, and the second retention region is configured to store data for a second predetermined period of time. The processor is configured to i) initially store, within the first retention region of the memory, the data that is received, and ii) in response to the data that is received having been stored in the first retention region of the memory for a time limit that exceeds the first predetermined period of time, transfer the data that is received from the first retention region of the memory to the second retention region of the memory.
