Abstract
A one-time programmable (OTP) memory can be programmed over a number of programming sessions in which each programming session writes a different portion of the memory. To provide the OTP memory with data integrity check capability, the OTP memory stores multiple error detection code entries. With each programming session, a new error detection code is stored in a previously unused entry. When the OTP memory is read, the error detection code corresponding to the latest programming session is used to verify the content of the OTP memory.
