PermSRAM is a versatile nonvolatile memory macro available on foundry standard CMOS platform covering process node of 180nm to 28nm and beyond. The series features wide varieties of nonvolatile memory functions 1) one-time programmable ROM and pseudo multi-time PROM incorporated with multi-page configuration, 2) wide memory size of 64bit to 512Kbit, 3) non-rewritable hardware safety lock for security code storage.

TwinBit performs the electrically erase operation for min. 64bit to max. 512K bits memory density and serves as a true electrical rewritable memory technology up to 10K P/E cycling with zero additional masking layer. TwinBit technology is very similar to the PermSRAM and has almost compatible macro interface.
