Abstract

A one-time programmable (OTP) memory device includes a memory array. The memory array includes: a data storage section for storing application data; a verification information section including at least one verification information unit, wherein each verification information unit includes a verification address region for storing verification address information associated with an address of a subject region in the data storage section, and a reference verification data region for storing one or more reference verification data, and wherein each reference verification data is calculated through reference verification calculation on the application data stored in the subject region using a predetermined verification algorithm. The OTP memory device further includes a verification processor for reading the application data from the subject region according to the verification address information, and calculating a self-verification result from the application data stored in the subject region using a selected verification algorithm; and a controller coupled to the memory array and the verification processor, for receiving the self-verification result from the verification processor and comparing the self-verification result with a reference verification data selected from the one or more reference verification data stored in the reference verification data region to obtain a comparison result.
