WAYS OF IMPROVEMENT OF NON-VOLATILE MEMORY DIAGNOSTIC TESTS BASED ON EXAMPLE OF DETAILED MARGINAL READ TEST

Abstract

A non-volatile memory has become the inalienable part of any computerized or automized system and the correctness of the system work should be guaranteed during the whole lifetime over any environmental conditions. To foresee these processes there is a list of experimental researches, including climate and temperature emulations, postexperimental data analysis. Considering the results it is possible to make the assumptions on lifetime, deterioration, error presence and its’ correction. This article depicts the analysis on problem of non-volatile memory evaluation tests, key experimental conditions examples of use and corresponding results. Detailed Marginal Read(DMR) readout algorithm is described, the error distribution over reference voltages graph is built and highlighted the drawbacks of this research. It is found that despite the fact that DMR is a memory evaluation common test for lifetime prognostication and end product in an application quality assuarence, it has a limitation. Also the experimental data is given with the proposals on a new algorithm of the test execution. Currently determination of the state of each memory cell the constant reference voltage step algorithm is used, so partially the results are noninformative. Based on the previously implemented experimental setup, used for the test reproduction and evaluation, gained the initial results and improvement assumptions are made. The DMR improvement possibility based on a binary lookup algorithm and informative area determination is depicted. Such an approach allows to shorten the iteration number for up to 28% which corresponds to 1.5 - 2 hours. This should lead to a tested memory volume per hour increase or would give an opportunity to perform a deeper memory state analysis in a saved amount of time.

Энергонезависимая память, которая является неотъемлемой частью любых компьютеризированных систем, по своему назначению должна безотказно работать в течение эксплуатационного срока в различных условиях окружающей среды. Для исследования процессов старения памяти и прогнозирования потери данных существует ряд экспериментальных опытов, таких как климатические, температурные, возмущающие и т.д. После обработки полученных данных, принимается решение о сроках использования модулей памяти, степени износа, наличии и коррекции ошибок в необходимое время.В статье представлен анализ проблемы оценки состояния энергонезависимой памяти на примере Detailed Marginal Read (DMR) теста. Приведено описание алгоритма DMR, проанализирована зависимость распределения ошибок по уровням вычитки и выделены недостатки указанного алгоритма. Показана возможность и подтверждена эффективность улучшения алгоритма DMR за счет использования классических алгоритмов поиска.

Енергонезалежна пам’ять, яка є невід’ємною частиною будь-яких комп’ютеризованих систем, за своїм призначенням має безвідмовно працювати протягом експлуатаційного терміну у різних умовах довколишнього середовища. Для дослідження процесів старіння пам’яті і прогнозування втрати даних існує низка експериментальних дослідів, таких як кліматичні, температурні, збурюючі і т.д. Після обробки отриманих даних, приймається рішення про терміни використання модулів пам’яті, ступінь зносу, наявність та корекцію помилок у необхідний часовий проміжок. У статті наведено аналіз проблеми оцінки стану енергонезалежної пам’яті на прикладі Detailed Marginal Read (DMR) тесту. Приведено опис алгоритму DMR, проаналізовано залежність розподілення помилок за рівнями вичитування та виділено недоліки зазначеного алгоритму. Показанo можливість та підтвердженo ефективність вдосконалення алгоритму DMR за рахунок використання класичних алгоритмів пошуку.
