PermSRAM is a versatile non-volatile memory solution integrated into foundry standard CMOS platforms accommodating process nodes from 180nm to 22nm and beyond. This memory technology offers various functionalities, such as one-time programmable ROM and pseudo multi-time PROM, which feature a multi-page configuration spread across memory sizes from 64 bits to 512K bits. A notable aspect of PermSRAM is its non-rewritable hardware safety lock that ensures the secure storage of critical security codes.
In addition to its security features, PermSRAM delivers high reliability and a stable yield, making it suitable for automotive applications that require data retention at temperatures exceeding 150 degrees Celsius. This memory type is designed for seamless integration with existing system infrastructures as it doesn't need additional read operation circuitry like charge pumps. Its built-in self-test circuit is pivotal for supporting stress-free testing environments, ensuring ease of implementation in various applications like DRM and HDMI decoding, security code storage, and program storage.
The benefits of PermSRAM extend to a smaller silicon footprint, achieved through a tamper-resistant design mechanism that uses an invisible charge trap memory system. This compactness is complemented by a fully testable architecture using conventional equipment. PermSRAM beams with capabilities that cater significantly to secure and reliable memory demands, whether for market differentiation or meeting stringent automotive standards.
