PermSRAM is a sophisticated nonvolatile memory macro designed to operate on standard CMOS platforms, spanning process nodes from 180nm to 28nm and beyond. It supports a wide variety of nonvolatile memory functions, including a one-time programmable ROM and a pseudo multi-time PROM with exceptional multi-page configuration capabilities. The memory sizes range from 64 bits to 512Kbits, making it highly versatile for various applications. It features a non-rewritable hardware safety lock, specifically for secure code storage, ensuring data integrity and security.\n\nPermSRAM's robust design supports security code storage, program storage, and analog trimming, among other applications. It also provides features like gamma correction and chip ID management, making it suitable for complex tasks. The memory benefits from a compact silicon area, being tamper-resistant due to its invisible charge trap mechanism. Its built-in self-test circuits ensure seamless testing environments and all bits can be tested using conventional test equipment. Furthermore, it offers automotive-grade data retention capabilities, functioning optimally under high temperatures.\n\nCustomers benefit from its cost-efficiency, as it does not require a charge pump for read operations, which simplifies the design and lowers costs. The product's compatibility with conventional test strategies and its suitability for high-temperature environments make it an ideal choice for automotive applications and other demanding industrial uses.
