Impact of the erase algorithms on flash memory lifetime
2017
This paper presents a comparative study on the impact of the erase algorithm on flash memory lifetime, to demonstrate how the reduction of overall stress, suffered by memories, will increase their lifetime, thanks to a smart management of erase operations. To this purpose a fixed erase voltage, equal to the maximum value and the maximum time-window, was taken as the reference test; while an algorithm with adaptive voltage levels and the same overall time-window was designed and implemented in order to compare their experimental results. This study was carried out by using an innovative Automated Test Equipment, named Portable-ATE, tailored for Memory Test Chip and designed for performance e…
Reconfigurable digital instrumentation based on FPGA
2004
A novel application of FPGA to realize digital test equipment is proposed. It takes advantage of the dynamic reconfigurability of FPGAs so easily tailoring custom test functions in the same instrument. This results in high effective, compact and low cost instruments.
A novel noise figure and gain test set for microwave devices
2002
A new instrument for the measurement of noise and gain of microwave devices is presented. It differs from the commercial ones in the accomplishment of the gain measurement and is also useful for measuring mismatched devices such as transistors, The instrument is driven via HP-IB by a PC and a user-friendly virtual panel is designed to perform all the required operations. Also included is the possibility of removing the second-stage noise contribution and correcting various sources of error (source ENR variations, temperature variations, etc.). The test set provides a very good accuracy for both matched and mismatched devices, usually limited by source ENR accuracy and step attenuator repeat…
Performance evaluation of non volatile memories with a low cost and portable automatic test equipment
2017
This paper presents a versatile and portable test equipment, called portable ATE for research and development of non-volatile memories functionalities. The system is based on STM32-NUCLEO assembled with a custom designed daughter board, in order to host non-volatile memories test-chips, to manage the needed power supplies and generate suitable signals stimuli for correct operations. The system is controlled and programmed by a personal computer, via USB interface. In particular the system can perform: memory reading, writing and erasing, with settings flexibility on time and voltage levels; Electrical Stress Tests (Drain, Gate and Bulk Stress); Cycling Tests; debugging algorithms (erase or …
