Abstract
Aspects of the invention provide for masking a current profile of a one-time programmable (OTP) memory. In one embodiment, a circuit includes: a first one-time programmable (OTP) memory configured to receive a data input for a plurality of address fields; and a second OTP memory configured to receive an inverse of the data input for a plurality of address fields, wherein a current profile for a programming supply for the first OTP memory and the second OTP memory is masked, such that the data input for the first OTP memory is undetectable.
