PermSRAM offers a flexible non-volatile memory solution designed for seamless integration with standard CMOS processes from 180nm to 28nm and potentially beyond. Its key features include one-time programmable and pseudo multi-time capabilities with a variety of memory configurations, ranging from 64 bits to 512K bits. Notably, PermSRAM incorporates a non-rewritable hardware safety lock, which is ideal for secure storage of codes.
This memory macro caters to applications requiring high security and reliability such as security code storage and program management. It provides a robust solution with stable yield performance, making it an excellent choice for various security-sensitive uses. Furthermore, it eliminates the need for additional charging circuits by operating with a typical system board voltage of 5V, which leads to significant savings in silicon area.
PermSRAM is structured to handle stress-free testing environments thanks to its built-in self-test circuits, maintaining efficiency even under demanding conditions. Its small silicon footprint and highly secure data storage make it suitable for a comprehensive set of applications, including analog trimming, gamma correction, and chip identification solutions.
