Reliability Evaluation of Programmable Read-Only Memories (PROMs). Part III:Ultraviolet Erasable PROMs.

摘要

Ultraviolet erasable programmable read-only memories (UV-PROMs), type 2708 and 8192-bits capacity, were evaluated. Military grade parts were obtained from two manufacturers. All parts were put through screening tests for package hermeticity, erasability, programmability, and electrical performance. A Tektronix S-3260 automatic test system was used for electrical measurements. 'Shmoo' plots showed that these UV-PROMs can operate with power supply tolerance of + or - 10 percent at -55 to +125 C. Retention of data during storage was found to be adequate.
