Cypress’s anti-tamper memory, based on nonvolatile static RAM (nvSRAM) technology, has unique features that protect SRAM and nonvolatile data from accidental or malicious intrusion. It also provides the fastest nvSRAM function. This white paper describes the tamper protect features implemented in the Cypress anti-tamper memory such as password protection, data destruction, functional destruction, and physical destruction. It is also possible to customize a combination of these data destruct features to suit application requirements.
