Abstract
A memory system is configured to convert multiple programmable memory or a portion thereof to one-time programmable (OTP) memory. The system is configured to repetitively perform memory operations (such as program and erase procedures) on a portion of memory in order to induce accelerated degradation (aging) of select memory cells, thereby permanently changing the select cells, such that a pattern of the cells with degraded performance indicate a data value that has been permanently encoded into the memory.
