Electronic system subject to memory overflow condition

A system, comprising:

• a first memory configured to store information corresponding to an input data stream, wherein the first memory has a first operating rate;
• a detector configured to detect an overflow condition of the first memory and to generate overflow information in response to the detection of the overflow condition;
• a second memory configured to store the overflow information, wherein the second memory has a second operating rate slower than the first operating rate;
• a third memory configured to receive the overflow information from the detector at a first transfer rate corresponding to the first operating rate, to temporarily store the overflow information, and to transfer the stored overflow information to the second memory at a second transfer rate corresponding to the second operating rate;
• and
• a combiner configured to combine the information stored in the first memory with the overflow information stored in the second memory to produce an output data stream.
