PermSRAM is a dynamic non-volatile memory macro designed to be implemented on standard CMOS platforms, spanning process nodes from 180nm to 22nm and beyond. This memory technology offers a suite of functions including one-time programmable ROM and a multi-time programmable ROM, adaptable through its multi-page configuration. PermSRAM covers a wide range of memory sizes from 64 bits to 512K bits, making it versatile for numerous applications.
The memory ensures security with its non-rewritable hardware lock, ideal for storing sensitive security codes. Its invisible charge trap memory mechanism makes it tamper-resistant without needing a charge pump for read operations. Furthermore, the built-in self-test circuit simplifies testing processes, supporting conventional test equipment for ease of use.
Targeted applications include analog trimming, program storage, and memory repair, among others. The PermSRAM memory is also optimized for environments demanding high reliability, with proven stability and superior performance. Its capabilities make it an excellent choice for sectors that require robust data retention, even at automotive-grade temperatures exceeding 150 degrees Celsius.
