The ReRAM Click Board™ features ReRAM (Resistive Random Access Memory) module which contains the cell array made of 524.288 words x 8 bits, which totals 4 Mbits of data. The used memory module can withstand a large number of write cycles, it has data retention period greater than 10 years and it can read and write to random addresses with no delay. Besides these features that already mark this kind of memory modules a milestone in memory manufacturing technology, the device features block write protection, low power consumption and fast SPI interface that can theoretically work up to 5MHz. Because of its universal memory characteristics, the ReRAM Click Board™ can be used both as a non-volatile storage media, or temporary RAM expansion for storing variables in any embedded application.
