Firstly, let’s see the conclusion that Renice draw based on the test from Nand Flash test platform NFA100. 1, the P/E cycle of some Block up to 20,000 times in real test, though it said only 3,000 times in datasheet. 2, Each block is an independent individual, and the initial condition of each block is not exactly the same, even though they are the same process in the same production line. 3, No matter it’s original Nand Flash or non-original, they have the necessity of testing, the Nand Flash can be sorted and classified into different levels. 4, Though it is the same Nand Flash chip, the health condition of each Block is not the same 5, The real lifetime (P/E cycle) of Nand Flash may be far greater than its datasheet, only when test, it can play the greater value. 6, Deep understanding of the life performance of Nand Flash in different P/E stages can help better plan ECC. 7, For those who want to convert MLC mode to SLC at a certain stage, when to start ...

If all Page performance is basically the same when programming every time, this Nand Flash chip should be the most stable and reliable. Therefore, you can know the reliability of Nand Flash by observing the distribution of each Page performance. Although the datasheet for each Nand Flash chip will indicate detailed time of Erase, Program, and Read Performance , in fact, these Performances average the Lower page and the Upper Page, so it will mislead people that the performance of each page is the same, actually it is not. Renice test setting and idea: Take a new 3D Nand Flash for example, choose 1024 (03FF) Block, Program/Erase for 1000 times. The more stable the graph shows, the more reliable the Nand Flash is, if the graph floats drastically, the worse stability of the Nand flash. It looks stable when Page0 program A not ideal Lower Page test result as following. A not ideal Upper Page test result as following. Conclusion: the...

If you want to look for a Nand Flash test equipment, Renice have 3 types of Nand Flash Tester for your option, NFA100-E, NFA100 and NFA1000. What can Nand Flash Testers do? How to select a suitable Nand Flash Tester? Let us show more information, you might find the answer here. Brief Introduction NAF100-E , is an extremely powerful and flexible NAND Flash testing platform specially developed for R&D personnel whereby they can extract NAND Flash parameters in a maximal way by using NFA100-E system commands and even reprocess these parameters for eventual product development. User can also realize their specific testing requirements through API or usage of script commands. NAF100 and NAF1000 , is able to test up to 112pcs/1120pcs of NAND Flash at the same time. Besides all functions that NFA100-E has, NFA100 is equipped with high-low temperature chamber so that users are able to make high-low temp. cycle test, humidity and thermal shock test.NFA100 is also ...

VDR (Voyage Data Recorder) is an instrument continuously recording real-time data of ship body, including speech communication signal of cockpit, sensors data, alarm status and radar images , at the time ship breaks down. Before deployment, VDR is tested and approved to be resistant of fire, puncture and deep immersion to make sure the data is well stored and recoverable after accident happens. Based on these data about ship navigation and operation, accident investigation will go smoothly and root cause could possibly been found. Nowadays technical trend of VDR is to expand the data collection range (e.g. including video signal) or extend the recording time (24 hours or longer). To achieve such goals, capacity of the storage has to be larger. Thus in near future storage solution used by VDR should enlarge the capacity to maximum extent while guarantee the reliability as well. However because of the harsh environment of ship navigation and electromagnetic interference release...

Background -Passenger Information System Public transportation passenger information system is one of the important part of public transportation system. Passenger information system(PIS) provides multiple transport means information to passengers before or during travels. Among the passenger information systems, the system mainly provides public transportation information is called public transportation passenger information system. International market: Developed countries take passenger information system as an important sector of intelligent public transportation for study. Countries like US, Japan, Canada, UK, France, Korea invested great human and material resources working on intelligent public transportation systems and got notable achievements. Domestic market: Our public transportation passenger information system is still at startup stage, information inquiry is single and lack of rationality. Although public information service system base on internet or teleph...

Учитывая, что SSD должен основываться на FTL для реализации передачи данных между логическим адресом и физическим адресом, если при нормальной работе (чтение / программа / стирание) происходит ненормальное отключение питания, это может привести к потере таблицы отображения, которая имеет не завершено обновление и в результате SSD не удалось обнаружить хостом. Между тем, чтобы улучшить производительность чтения / записи, SDRAM обычно принимается в качестве буфера на плате SSD. Аномальное отключение питания также может привести к потере данных или обновленной таблице сопоставления, которые не были записаны в NAND Flash из SDRAM. Проблема сбоя, вызванная аномальным отключением питания 1. SSD не может быть обнаружен ОС после внезапного отключения питания, он может быть повторно использован после повторной сборки таблицы сопоставления или замены. 2. Массовый новый плохой блок, созданный после неоднократного аномального отключения питания. Механизм создания нового плохого блока: ког...
