A system and method for processing data streams is disclosed. The system receives data packets for data streams, screen the data packets for searched patterns, and forward the data packets for their respective stream processing. Generally, the data packet is scanned for viruses before being forwarded for further processing. When an out-of-order data packet is received, a copy is made and the data packet is forwarded without being scanned. When a delayed data packet is received, it is scanned for virus along with the saved copy of the out-of-order data packet. If a virus is detected, the delayed packet is dropped and its connection reset. If no virus is found, the delayed packet is forwarded for further processing.

A method of screening EEPROMs for data retention quality employs a UV source which is arranged to be impinged upon the devices while in wafer form, at or near an electrical probe station. Known data is stored in memory cells on an EEPROM chip while the chip is in wafer form, at a probe station. The wafer is then moved beneath a UV silo near the probe station and exposed to UV light, for a period of time and at an intensity which is sufficient to cause leakage of charge from potentially leaky floating gates. The wafer is again subjected to electrical probe where the amount of change in retained charge is detected. From this test, an indication of the charge retention ability of the devices is obtained. The UV light increases the energy state of the stored charge thus accelerating the decay of the stored charge located on the floating gates in the EEPROM device. Bits that have inherent leakage paths decay more rapidly.
